Broadly speaking, one of the biggest indications that your partner might be unfaithful to you is that their behavior suddenly undergoes drastic changes. To be clear, cheating isn’t the only reason this can happen. Stress at work or in their personal life can be the cause, too. But so can an affair.

For example, your significant other might suddenly change how they communicate with you, how they dress, how intimate they are with you, what their interests are, etc.

Changes in technology use are often a big red flag. For instance, it’s incredibly suspicious if your partner suddenly changes the passwords to their phone or computer without sharing them with you.

Something else that’s super sus is suddenly becoming unreachable during certain parts of the day, texting or calling someone in secret, and constantly clearing browser history.

Other signs of tech-related cheating to look out for include exercising during odd times and hours on your partner’s fitness tracker, suddenly switching off cloud sharing on devices, and stopping the use of shared devices.

With the ease of access to the internet and social media, these days, affairs (physical and emotional) are easier to have.

Verywell Mind warns that unless you have hard evidence that your partner is cheating on you or they tell you, they’ll likely deny any accusations you throw their way.

You may want to consider either couples’ or individual counseling if your significant other keeps avoiding discussions about your relationship. These professionals can help you deal with the emotional fallout and help you decide what to do next.

It’s hard to say why someone cheated on their partner without knowing their personal circumstances. Some individuals have affairs because they’re falling out of love with their significant other or because they’re angry at them.

Others might have serious commitment issues or don’t have their needs met. Still others desire more variety in their life, have self-esteem issues, or simply have the opportunity to be unfaithful, so they take it, Healthline notes.
