Normally with guys like that, they're the ones cheating and they press you because they want a justification for their actions and someone to put the blame on that isn't themselves. At least you got out OP.

If he has been suspecting you of cheating, chances are he was cheating on you way before. Only reason a guy will feel guilty about his significant other cheating is so that he can "justify" his cheating. Sorry OP, but if he couldn't trust you one bit you deserve better. His loss.

The best defense is a good offense?

I'm going to be 100% honest. I have NO idea how people end up in long term relationships like this. I mean 4 months isn't really long term but I've seen countless relationships where the person is made to feel like crap or they are accused of cheating, they are cheated on, fight nonstop, etc. I've never been in a single relationship like that. if the man is disrespectful to me, doesn't trust me, or we can't get along BYE! Obviously they weren't the one for me. People, men and women, need to learn when to cut their losses and find someone that makes them happy. 3 year anniversary for me and my boyfriend, best guy I've ever met. <3

Same thing happened to me. A boyfriend would constantly remind me to not ever cheat on him, to the point where he'd even threaten me if I ever dared. Turns out he had been cheating on me the whole time. Hypocrisy is everywhere

This is actually very common, thy accuse you of doing things they're doing themselves. They know they're capable of it so he worries you are too.

People that afraid of their SO cheating are either cheaters or have been seriously messed up by a cheater who claimed to be afraid that their partner would cheat in the past...

You need help....

Worst excuse ever

that's me. except that it was 4 years
