Phew! Ciluzen, your H certainly seems to still be on a huge roller coaster! What a change in behaviour from him asking you out for dinner only a few days before! I know exactly what you mean about not asking him for help. I am trying to do everything without asking for help from H. I don't want him to think I am helpless without him. The only thing that has come up so far that I couldn't do myself I got my Dad to help me instead.
I hear you on the major losses too. There is so much loss in these situations, of every kind. Maybe your H is suddenly realising the enormity of what he is losing. Up until now he has lost the house because he no longer lives in it, but it is not totally lost as he can still visit it. That is soon to change and it is probably making him think more than he is letting on.
Keep being the amazing person you are. You are doing so well.
