Hi d_rose. So sorry to hear about all of this. Your husband seems similar to mine in that he is generally pleasant and wants to keep a relationship with you on his terms only. For me the hardest thing has been to stop him from talking about the R. I even sent him an email (our conversations go better that way) explaining in no uncertain terms that I do not want to talk about the R unless it is to work on the R. He did not respond, so who know...
Good luck. Keep your expectations low and plan for life without him. I also agree with everyone, don't be home when he comes - don't engage. He's not your friend - at least not right now - so make other plans.
Hang in there!
