Are you willing to accept him back if that proves to be true? Im just wondering. If so then it might be a good thing for you that he doesnt consider that a relationship. Maybe he doesnt really care about her at all. I know that I have done that a time or 2. I didnt go into it being a a$$hole or anything, it just turned out that I really didnt end up caring about them when I got into it further. I think your sitch has plenty of hope if you are willing to do the work that it will require.
