He sounds alot like my H with the back and forth and distant behavior. You really have to consider your H is having an affair - even an EA for sure. That's what it seems like to me.
Did you get the DB book? start reading and read up here at others' situations. I'm really sorry you're going through this. We all understand.
Stop pursuing your H and work on yourself. The more you lean towards him the more he will pull away.
