Thanks a lot everybody! I'm sure there is something about his childhood as Job suggested. He has never felt loved by his mom but he says he's a grown up and that he accepts that she doesn't love him and that's it. But he has complained about the same thing about me.
The thing is that whether his problem arises from mom issues or not, that's how he feels about me and I feel that if I step away he may believe he was right all along about how he felt in our R.
But then, if I keep pursuing and things stay the same , am I enabling or stopping the whole process?
