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

Cheating is much more than a one-time practice. Once done, it could have adverse effects on the parties involved due to constant feelings of guilt, insecurity, emptiness, loss of control, and other negative emotions. He is most probably ignoring you because of those emotions confronting his conscience.

May be the guilt haunts him?.. Usually at these situations... People feel guilty for what happened and try to make the mistake right... This might be a step to reconsider himself..

Because he doesn't value you, just like he doesn't value his girlfriend. You don't want to be with a cheater do you? If he cheated on her, he will likely cheat on you too.

he might be ignoring you because he's trying to be around his girlfriend

That fact is he is a CHEATER! Why would you expect any other behaviour. The fact is why would you expect him to behave any differently with you? He is a total gem. Personally I think you need to take time out and get in touch with yourself. You helped him cheat on a girl- is this what you think you are worth? Please find some self love and find a single guy to be with. Always ask the question as to how a guy status wise before starting a new relationship. Get to know each other as friends and wether or not you meet his friends and family. Cheaters get what cheaters get.

He may be feeling guilt for cheating. Maybe she found out about the two of you. You should confront him about what is going on.

He may feel guilty about hurting her and also hurting you, I would give him so time to sort out these emotions.

Sounds like he’s not a good guy if he’s willing to risk two hearts. Remove this type of negativity from your life!

He has not been fair to either you or his girlfriend. It is easy to question and blame ourselves and wonder if it is something about us that is causing another person to act this way. The truth is that a person who follows this kind of pattern of behaviour will do this to everyone they encounter. It is not as though one miraculous person can fulfill their voids to make them happy. He will do this repeatedly to others over and over again in a vicious cycle. This person is an energy vampire and has nothing to do with anything about you. You are not the one at fault here.

Firstly, you must feel confused and saddened by your circumstances. I’m sorry to hear it. You can’t ever know with certainty without that person telling you themselves. It is possible this person decided to be honest with his girlfriend and try to work it out. This is why getting involved with people who are already in relationships can be very emotionally turbulent. Truly, if you knew the answer, would that make you feel any better? Do you really want to be with someone who cheats? If someone cheats on one partner, there is no guarantee that they would not do it to someone else. Hope you can gain some clarity soon. Best wishes.
