P, part of the thing to consider is that living under the same roof is a *chance* to reconcile things. Not necessarily save your marriage, but reconcile. Living in separate houses makes that more difficult. That doesn't mean you should contort yourself to be what you think he wants. That's a crazy path that will drive you insane But it is to say that close proximity is helpful if it works for you. No matter what, be you and let him be him.
