Just my two cents here... I don't have a lot of experience with breaking up, etc... I had several relationships before I married that didn't end well and have now been with my wife for over 20 years (Married 15 years this month)...

But, I do have some thoughts about this anyway. First, I feel like for your mental health it's probably good for you to begin to separate from him emotionally or to try and work it out. You obviously have very strong feelings for him still as you are talking with him regularly.

My second thought is about the physical attraction. I guess I don't really know what you mean by the physical attraction part, or at least the level of "not much". For me, the women I was attracted to before I got together with my wife were not emotionally good for me but the physical part was really good. My wife and I were friends for over 2 years before we decided to get together and the physical part never had the intensity of those other few relationships I had before. I think for me the intensity of the physical part often had to do with something unhealthy, and I'm not saying it's like that for everyone. My wife was my friend first, and that helped me. I don't do trust well, especially back then, so that was more important. And as time went on the physical part has actually improved as our emotional closeness and trust has grown even more!

Only you can decide what is best for you, but thought I would offer my thoughts about the subject. Thanks for posting this and I hope you come to some peace about this. I do feel it's best to make a decision one way or another because it seems to be hurting you emotionally to try to just be friends with him.
