We separated 6 months ago, our relationship was awful, we both agree now. While we were separated, she tried to get me to come home, I was still hurt and upset, I told her I didn't want her anymore. A couple months went by and she started dating, and so did I. We recently(2 months ago) decided to leave the people we were dating and in love with to try and make things work again, given our new outlook on our problems we had. I never committed with sex with the person I was dating, and I was somehow under the misunderstanding she didn't either. I brought it up one day and she said" I never said I didn't", I was crushed, I felt dead inside that instant. I was falling in love with her all over again, and bam, it died right there. I flipped out on her and told her I didn't want to try anymore. She still came back and didn't give up on me. We've been still working on things, but I'm still going insane inside knowing another man had my wife, even though I know we technically weren't together, I'm still very much heartbroken over it. It consumes me when I'm not around her, gets me so angry with the guy she was with. All of this isn't the worst part..I now have this obsession with thoughts of her having sex with this guy, I had to know every detail of their sex life, his size, the positions he had her in, how much she anticipated him being inside of her, all of it. I really don't know how to get past this. I just want to fall in love with her again, and make her do the same with me, but I fear this won't go away. I have no clue what to do from here. I don't want to scare her away with questions anymore, so at this point I'm just keeping this stuff in my head. Anybody have any advice on how to start making this go away? I love my wife with all my heart, I know I'm responsible for what she did with him by telling her I didn't want her anymore. I'm sick inside, what do I do?
