have to agree with LTD that it really is an individual case.
In both of my relationships with the A - they kind of disappeared..they didn't try and get me back, didn't try and get sober.
They just moved on to their next relationship (pretty shortly after the one with me ended).
Sometimes it escalates, sometimes it doesn't.
You won't be able to understand him or his behaviors..once again look at the "whys" of what you do what you do.
You loved him - great...
Trying to figure out how much someone loved me just tied me up in knots.
