Wow - I just finished reading the whole thing. What a roller-coaster for you! Brian sounds like a piece of work - but I suspect you are right about his feeling threatened by your independence and willingness to take risks. I had a husband like that once. He would be supportive of my big decisions until I made them, and then tell me it was my fault for doing it if things didn't turn out well. Never any compassion or support in the rough times.
Anyway - it sounds like your physical healing process is going pretty well. It will be good when you can take care of yourself better, and don't have to depend on him. Seems like his "analysis paralysis" does get in the way quite a bit.
Sorry I didn't find this thread earlier - I would have been here supporting you! I wondered how you were doing.
