For many individuals, friends are some of the most important people in their lives; not to mention best friends. But unfortunately, despite often being referred to as “best friends forever”, they might not stick around this long, and there can be many reasons why.
One redditor recently started a discussion about such reasons, after they turned to the ‘Ask Reddit’ community asking why other users and their best friends had a falling out. Quite a few netizens went down memory lane—and not a fun one, I might add—and shared the stories of what turned their BFF into a stranger. Scroll down to find their accounts on the list below and feel free to share your story in the comments, if you, too, have lost a friend you thought was going to be by your side forever.
On the list below, you will also find Bored Panda’s interviews with evolutionary psychologist and expert in cooperation, altruism, and friendship, Dr. Patrick Barclay, and retired associate professor, researching positive and negative components of friendship, Morton J. Mendelson, who were kind enough to answer a few of our questions.

Her ten year old son died of sepsis.
a few years later, I survived sepsis, because I knew the signs.
but because I survived, our friendship failed. twenty years.

Let’s just say when you got through a health scare like cancer, you quickly figure out who your good friends are, despite being beside them through thick and thin over many years. Good riddance!

Invited him to an NFL game, ticket price was $100.00 or so, I didn’t ask for reimbursement or did he offer it, just wanted him to have a good time. Fast forward two weeks later, I call him up on a Friday evening seeing what he’s up to, want to do something. He’s excited I called because him and other friends, not my friends, had an extra ticket to a cover band, ask if I wanted to go. I met up near the venue, one of his friends became ill and so I ended up driving him home, over 20 miles round trip. Got back to the venue,went to the show, good time. Two days later he was over to watch football, as he was leaving asked if I had the $8.00 for the ticket, I reluctantly gave it to him, he could tell I was upset. He called me about 20 minutes later asking why I was upset, I told him first I didn’t ask for reimbursement to the NFL game and most importantly he wanted $8.00 for a ticket that they would have not used, had to eat , if I didn’t call. Also I reminded him of driving his ill friend home without any offer of reimbursement. His response, “oh.”.

He got into a relationship with a narcissist. His gf has been alienating his friends from day 1. Just found out from a mutual friend that none of his Day 1 friends are invited to his wedding. I’ve know my best friend for almost 2 decades.
Heard the reason why I wasn’t invited was because I didn’t support his relationship according to his fiancée. The fiancée has bumped heads with me in the past and I was his roommate but she wanted me gone. I stood up for some ppl in our friend group when he stayed silent while she gossiped about them.

Because I was a s****y, self centered, selfish person and they finally had enough. Even though it shattered me at the time, and still does from time to time, it may have been the greatest act of love they ever gave me.

I "left town and didn't even tell anyone." I messaged them all for months and even had a going away party that no one showed up to. Looking back they were not very good friends.
