Ma'am, I read your entire post, and I understand how you feel. I have given my all to someone. I had thought I finally found someone, then she did a 180. I have since shut down and stay away from people.

As far as answering your question, it sounds like he might have developed a split personality, to try and hide what he feels rather than accept he has a problem.

I know it is hard to move on after what you felt/feel for him. If you don't, you're going to hurt yourself more. You most likely know it will take time. You need to think of you. Remember the saying...."It is better to love and lost, than to never have loved at all." You sound like a strong person. Use that.
