Sara is right. H has never ONCE checked on me, just me, since he moved out.
Continue detaching and don't be available for all his calls, but don't keep your daughter (1 D, right?) from him either (if he calls to talk to her).
So sorry he left, but oh the silver linings!!! You can go to bed, not worrying about when he will be home or not. Its hard, but at the moment you both need space.
