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

He is just confused and needs time deciding what he truly wants. another reason could be his gf found out

You shouldn't have been with him if you knew he was cheating on someone else with you, that's a lesson you should learn from this experience. He wasn't trust worthy with his girlfriend and he shouldn't be with you. Much love!x

Perhaps it is because he feels guilty about his choices. His infidelity may have made him realize that he cares about his girlfriend and wants to continue that relationship. Interacting with you reminds him that he made a mistake that violated the trust they should have.

Oh I've been through that! From my experience, I think he is ignoring you because he feels guilty, even though he wanted to do that. He probably feels bad because he broke his girlfriend's trust. If you put yourself in his shoes, you'll probably have many negative thoughts and you'll think little of yourself. It feels unethical. You're hurting someone you care about but yet you want it. After cheating, you're terrified of the consequences. That is my opinion about why he is ignoring you.

He was committed when he met you, you could've asked him to leave her for you but he wanted you as an other option he had, don't be someone's choice if he actually love you he will break up with her and come to you, but as you said he is ignoring is because he justed wanted to use you, you should hate him for what he did to you, even his girlfriend isn't that lucky to have someone unfaithful, so be happy you got off from being in that position, find someone who truly loves you as who you are and cares about your feelings trust me there is some guy waiting for you to notice him, who loves you no matter what and will never leave you, the one with whom your life is meant to be.

So now it comes your turn to get cheated by him. You were his partner in crime. You were the reason of someone's tears. I don't know why you involved with him in cheating that girl. What you got by helping a guy to cheat with a person? There is something called karma which is now following you. What you have done with that girl now another girl may be helping that guy cheat on you. He used you as a bait. He just used you for some purpose and as the purpose is over now he will stay away from you. You better ready to cry now.

Maybe he just needed to try something new and now he is blaming him for cheating on someone, he is not comfortable with it.

He probably feels guilty about cheating on his girlfriend. Talking with you could emphasize his guilt for what he did.

She cheated on her boyfriend with me. Why is she ignoring me? Something drew her to me. Was it my charm or his under-appreciation? I made her feel special, I made her feel something... We connected on more than one level. Why is she ignoring me? It's most likely guilt. Or was I just waters for her to test. Either way I don't regret it, I hope she feels the same.

Maybe he found another girl because if he will cheat on one girl for you then he will repeat the process.
