I can't love my girlfriend and its MY fault!

My girlfriend and I have been together off and on for over two years. We have had a rocky relationship with several breakups and fights. 8 months ago we broke up for two months. been back together for 6 months. Recently I found out she had sex with another man during our breakup. I am crushed and devastated! BUT I SHOULDN'T BE because I did the same thing with several several girls. She doesn't know about the girls. Despite the fact that I did it too I am still so sad and hurt!I can't eat or sleep and when I am with her all I think about is her with the other man. It absolutely consuming my thoughts. I need help!! Tough love welcomed!

I'm not sure if I should answer this or not but I will go ahead. It is easy for us to judge others for the mistakes that we ourselves make. Every one knows that. So lets look at this another way. Why did you sleep with others while on the break? Maybe you two have a too much of a rocky relationship. Maybe this was a good thing that she slept with another man. Be honest with her and let her know about the other women. Then with all the cards on the table you can both decide on if this is too far gone to continue.

Thanks for the reply! I have thought about telling her about me sleeping with other girls but am scared. She didn't tell me. I had to find out on my own and then she lied about it until finally admitting it. She really wants to work things out and I thought if I just reminded myself enough that had done the same that I could get through it but I can't. Point it even if I tell her it will not stop these images in my head. Its terrible! Thanks again

If you can't let the past go, then you need to let her go. If she didn't tell you that she was with someone else, she most likely feared your reaction. We live and we learn...we all make mistakes, what matters is that we learn from them. It's hard to let the past go, just remember that everything happens for a reason. Maybe she learned a lesson. Don't torture yourself and don't torture her if the past is going to be an ongoing issue. I wish you the best! I've been there myself...on both her end, and your end.
