After 4 years my ex and I broke up. I found him "serial cheating". It's been a year now and we still talk but it affects me every day. I can't seem to move on and I actually feel guilty if I meet a guy and we have sex. Today I broke the cycle and told ex that I don't want to see him, talk to him, receive email/texts etc from him. He said "you're acting like a child". I shot back that this is exactly why I don't want to see him anymore; he's treated me as inferior for too long and I need to move on. I thanked him for his comments and hung up. He called back repeating that I'm acting childish and that there's no reason to be doing this. I explained all of the above - that I can't move on so long as we are connected. In order for me to survive I need to have distance. I told him that he seems to have moved on with his dating etc but I can't seem to do that as well as he has. I told him I still have feelings for him and still hurt over what happened and the only way for me to survive is to move on without him around me. I said "I'm taking back my friendship" and it's over. Every muscle in my body is now tense. Shit!
