I strongly recommend you stay put as long as there in n abuse. If there is, he should go.
Still living together has given my H and I a number of unplanned opportunities to reconnect that would have been much harder if we were not living together. I have the opportunity to show H changes and GAL more easily as well. Since we do not have children, reasons to connect would few and in between. I think this is what is causing him his confusion and maybe giving him pause about whether D for us right path. I think you can still find ways to make him miss you living there.
