My ex bf and I got back together. Our relationship is better than the first time around but he still hasn't let go of his gf although he has told her he is having a relationship with me. She agreed given the mess their relationship is in and they can't fix it no matter how hard they have tried. but, but he still loves her and she loves him. I can and do fill his important emotional and sexual needs where she cannot. Her important needs are not met either. this I have heard from the both of them. But they have a close friendship and want to hold on to that. They also fight a lot and have never been able to live together for this reason alone. Now as an off shoot of his relationship with me he is more calm around her and there is less stress between the two of them because he is getting his needs met by me. I did not enter into a relationship with my ex to improve their failing relationship. Somehow I feel angry and used. Is it just me? He said that I feed him and she dosen't. Should I just walk away and let their relationship fall apart and tell him to come to me then? and If ?
