He cheated on his girlfriend with me. Why is he ignoring me?

He might be ignorning you because he feels guilty for cheating, and communicating with you might bring up those guilty feelings once more. He might be debating on whether or not he should tell his girlfriend or just break up with her (so that he won’t have to confront her about the issue). He’s likely just trying to work through what he did and figure out what the best outcome for everyone in the scenario would be.

Maybe he feels bad for doing that, he could possibly be regretting that situation and is causing him too be depressed when he talks to you because he thinks about what he’s done.

Because that is a sin and something bad and unrighteous will always end up badly as people have consciousness and they will surely think of what's good and bad and what is beneficial and acknowledging beneficial and what is not will give the idea in the mind that you should leave and ignore me

Maybe he has allot on his mind after all he cheating on his partner so He probably is feeling lots of mixed feelings.

because he feels guilty of his actions and doesn't want to continue the relationship any furthere

More than likely, he either feels guilty about cheating on his girlfriend with you. The other reason is that he is not having contact with you is an attempt to save the relationship with his girlfriend.

He probably feels guilty, or decided he wants to be loyal. It’s not right to cheat on someone, because if he wanted to be with you, he’d be with ONLY you. Maybe the girl found out and he wasn’t ready to leave her, so he’s ignoring you. Maybe he really just regretted it. Or maybe he’s just busy. I really can’t tell from the scenario. Either way, he cheated on his girlfriend, and if you dated him, he might cheat on you. Is that the kind of risk you’re willing to take? It’s your choice, but personally, I’d respect him ignoring you, and stay away.

He probably feels sorry for what he did to his girlfriend. Maybe he feels guilty now and wants to forget about you so that he can live his life without thinking about what happened too much.

he cheated on his girlfriend with you and is now ignoring you? have you possibly considered that he might have regretted what he did and is back with his girlfriend or might be doing the same thing with another women who isn't his girlfriend or you.let me just say any man who cheats on his girlfriend probably wouldn't have a problem doing it again and isn't worth even fighting over. it would be better to end things before things get even more complicated. but remember this is your decision to make and you should be the one who knows what the next step is to finding a solution. I hope you find the answer to your question

There could be many reasons why, but it's most likely since he realized what he's done to his girlfriend was wrong and regrets doing it and wants to change that, or he feels bad about it. I would move on, even if moving on is hard if you have genuine feelings for him, being someone's side piece is really unfair for you.
