I wonder to what extent this event is also affecting your H's PMA. It sounds as though he is really having a tough time emotionally and remember, it likely has nothing to do with you....but with his own thoughts in general.
Keep patient, keep up the good work. Remember, as you told me, you have set into motion a process that has seen many positives. Don't forget that. And while 5 months seems like an eternity to those of us that have been in this sitch, its only a tiny drop in time. Take that walk on the beach....watch the sunset, think of the good things that will come your way with a brand new day.
"Achieve success, but without vanity; Achieve success, but without aggression; Achieve success, but without gain; Achieve success, but without force." Lao Tzu
