Whew! I just caught up on your sitch. Was your H acting the same way when the D was called off last year? Is he willing to go to MC? I think you are voicing your concerns to him but he isn't hearing them, maybe a MC could help with this disconnect.
I usually wouldn't say you should pressure him to move back in but the problem is that your H runs when the going gets tough. At the first sign of conflict he leaves....maybe if he didn't have anywhere to run it would help. Right now he can just go to "his place", and doesn't really have to put anyone out.
From your last few posts on your other thread it seems he really wants to work on it. Give him a chance, but you have to stick to your guns if he doesn't follow through.
