31 Of The Darkest Secrets People Weren’t Supposed To Know But Found Out Accidentally

When I was 19, I walked into a retail shop to buy an outfit. When I got up to the counter to pay, I handed the young lady my credit card. Her response was "I know you." That made me feel good. Then she said "I know your dad, he's my dad." That was the day my siblings learned about our half sister. She's two months older than me.

I couldn't tell my mom, I know it would have crushed her. She found out later and was more upset that I didn't tell her.

Found out my ‘uncle’ was my dad and my ‘cousins’ were my siblings when i was 10. my little sister came to stay and i introduced her to one of my friends as my cousin. she asked me afterwards why i said that and i was like uh, because you’re my cousin? nope. 70s wife swap, they divided up the kids and my mother kept the truth from me. it’s been quite a life.

Not mine but a friend I know and his half brother decided to do a DNA testing kit (something similar to 23 and Me). When my friend (let’s call him Colin) was 2 years old, his parents divorced and his dad had custody. His dad remarried and had another son (we’ll call him Daniel). So Daniel and Colin grew up in the same household as half brothers, with the understanding that they share the same dad. Growing up, their dad always treated them equally.

Turns out, they’re not related at all. They don’t share the same dad.

The happy ending is they didn’t let that change their relationship in any way. They’re still close as ever.

That my late father was actually alive, but imprisoned. I found out when was 13. He had been out of our lives since I was around 4.

Ex-wife was most likely sleeping with her bio dad. They kept sneaking off to closed bedrooms to be alone.

I calmly confronted her about it and she got extremely upset and crashed out. The next morning she woke me up with my pistol pointed at me. I snatched it from her, and field stripped it. She then ran across the street with my kids (Not hers) and had a neighbor call the cops on me. She filed a restraining order while the cops were processing me before they let me go.

People don't behave like that if there's not a deep, dark secret to hide.

Side note, our justice system is a joke. Male victims seldomly see an form of justice. Attorneys and judges make many decisions based purely on emotion.

That my 66 year old Mom absolutely hated me and also writes erotic stories for some kind of erotica websites.

A few years ago she kinda had a mental breakdown and went missing for a week or two. This was shortly after my Dad had passed away and she hadn't been taking her meds or taking any care of herself. Her house was destroyed, every room filled with brand new stuff piled up. My brother and I filed a missing persons report and were asked to look around the house for any evidence of where she might have gone.

That's when I found a whole stack of notebooks filled with notes and stories. Multiple log-ins with words I never in my life heard her say, words I was surprised she even knew existed, all for erotica websites. Tons of stuff about her being used by men and enjoying it. I read about a dozen pages out of the whole stack because I hated violating her privacy, but then I found the book about me.

Page after page about me, how she thought I was manipulating my Dad in the months before his passing (he had moved in with me and had filed for divorce). She thought I forced him to file for divorce, had lists with things like: check accounts, were any pain meds filled at pharmacy, did I tell ER Drs to stop CPR, did I tell them not to contact her. It went on and on. I had no idea she felt this way about me, it was heartbreaking and infuriating. Makes and models of cars, license plates and the info and who was driving them and where. All people she suspected I hired to spy on her. She thought her car was being scanned by the government and had bought some magnetic panels to out in it's doors. So much paranoia and all of it based around me.

Even scripts of phone calls she wanted to make to me or others, detailing things like "say Hi then start to cry, tell story about... Then laugh"

suddenly every conversation with her that I could remember felt disingenuous and fake, I still have no idea who my real mom is because it was so bizarrely calculating and written out for me to find.

The cops ended up finding her a few days after I saw all of this. We tried for a guardianship but she was really good at evading every attempt made by professionals to be mentally evaluated, and we dropped it when she finally started seeing a psychiatrist and was stabilized.

She nor my brother have any idea I saw all the awful things written, and I can understand that she was in psychosis so I'm trying to move past it. She has since moved out of state and we talk every few months, she's totally pleasant with me, so it's really strange and I don't think I'll ever bring it up.

Edit: thank you everyone for all the responses, I didn't expect this to help me so much. I've realized I really need to look for a therapist, I've internalized a lot of th in ngs that will only snowball. I've cried a lot reading these comments, it's something I've held in for way too long, thank you so much for listening.

My brother accidentally let slip that our grandad didn’t go to (and pass away in) hospital but went to prison.

My dad’s infidelity history. A particular instance that hurts the most was another woman he married and got pregnant. All while stationed abroad and still married to my mom. I was probably 3yrs old.

I’m 45 now and he’s long passed away but these skeletons of his keep popping up. I have 3 half siblings that I know…so far.

So my grandmother had a lot of kids. Her first baby ever was stillborn, then she had 8 kids successfully, and the last baby she had was also stillborn.

That was the story until someone in our family added their DNA to an ancestry type website and found that BOTH of those babies had actually lived, been adopted, and are actually still alive with large families of their own. The youngest actually lives just a city away from us.

All of this was found out after my grandma had passed and while my grandpa was receiving end of life care, so no one ever got any answers about why these two were given up for adoption. We met the youngest at my grandpa's funeral, and she looks the most like my grandma out of all of the siblings.

Not quite as "dark" as some stories here, but it's the biggest family secret (so far)

Found out my “aunt “ wasn’t actually my aunt. She was my dad’s first wife. They never divorced. He just..left.Mom didn’t know either. We found out when the other family showed up at the funeral.

We found out during one of our visits to a cemetery, while looking at a small grave, that my mom actually had an older sister none of us ever knew about. We always thought my mom was the eldest, followed only by a younger sister.

Apparently, when the baby was still very young, my grandparents constantly fought, and one argument escalated terribly. Her father accidentally struck the baby.

Years later, it made us realize why our grandparents always seemed so bitter toward each other. It could have been the weight of that unresolved trauma they carried for the rest of their lives.

My mother is a public figure and uses a “stage name” for her last name. For decades the story has been that back in the day, her then-director came up with the name because it sounded better and provided more safety than people knowing her real last name.

A few months ago, I signed up for a family tree website because my grandmother on my dad’s side has done a ton of research spanning hundreds of years in our family, and I was interested in doing the same thing for my mom’s side and my grandmother wanted to do it with me.

When I was adding my mom to my tree, a few documents populated for me to review. I almost didn’t even look at them because it’s my mom and I figured there’d be nothing new.

No.

I found a marriage certificate showing she married a man with the last name (the “stage name”) that she has kept all these years. I’m not sure when they divorced but she married her second husband (who I have known to be her first husband my whole life) a few years later so a few years max. I know two things for certain: my dad doesn’t know this, and she doesn’t know I know. What I don’t know is why she would lie about it.

I haven’t told anyone.

my mother threw herself from a third floor and she never had an accident as everyone told me. i found it out reading medical papers. She survived and she’s fine ok

I was helping my tech-clueless uncle back up his old laptop to a cloud drive. Opened a folder labeled "Tax Receipts" to verify it copied, and found a massive archive of messages and hotel bookings revealing a second, secret family in another state.

My grandfather was 100% Polish. My dad doesn’t look much like him and I look a lot like my dad. I did a DNA test and turns out I’m 0% Polish.

My mom just admitted indirecrly during an argument that she was the anonymous call to the CPS saying my dad was beating me, same mother who pinned me and strangled me on a couch and psychologically mistreated me for years, worst part is i found out 15 years after

I know where my father went the night he passed away.

He was driving out at 5:00 in the morning while he had a heart attack. His long term girlfriend asked if I had any idea why he was out driving over in that area so early in the morning? They didn't live together, but had been together for least 10 years.

Well, I found out the answer when I went to shutdown his laptop. He was meeting some random dude for a gay date. Probably went out with a smile on his face as they say. I feel sorry for the other guy though.

I've never told a soul. I wiped the computer (as he had asked us to do), and never mentioned it.

We didn't have a great relationship, so I could care less what he was up to. He was never faithful to any of his partners, his gf broke up her marriage and his to be with him, she knew what she was getting into.

Just found out at 35 that my father has another son. Wtf. And he looks just like him.

I found out my grandma and her older sister are actually half-sisters. Turns out, my great-grandma got horribly beaten by her first husband and her brother and father were passing by...coming back from woodcutting. Carrying an axe. They only spent a few years in prison surprisingly.

When my first husbands mother passed away of cancer 33 yrs ago we were going through some old papers and I found my husbands parents original marriage license. Mind you we had always been told that his parents met, had a whirlwind romance and were married six weeks later. When she passed away they had been married for 34 yrs. Anyway… I pulled the marriage license out and said “ there is a huge typo in this”. My ex was born in 1966… this marriage license was dated 1967.

Come to find out, my ex father in law was NOT the father and was married when he met my mother in law. She was already pregnant but he chose to leave his wife and other son and married my mother in law. They lied about their entire origin story and that my ex wasn’t even his kid. She took it to her grave and he never has gotten closure. The only thing he found out was that his biological father apparently passed away in a random car accident when she was pregnant. This is something that still haunts him to this day.
