GF, your H says he doesn't want the divorce but all I think you've really asked of him is that he moves back in with you isn't that right? And he hasn't done so! And it's been 3 years which I think is clearly enough time for him to get off the fence.
If it was me, I would give him the choice of moving in before the divorce hearing or go through with the divorce now, and as you say if he later decided he wanted to reconcile you could always remarry later. But of course that's just my personal opinion and you have to make up your own mind of course!
And I think if your H moves back in, you will be totally fine judging by all the great advice you give me and everyone else here!!! Karen
