This is where I am as well. My husband and I work opposite shifts, so we don't see each other a whole lot except when he has a weekend off every other week, or some evenings when he's off. He hasn't really been in that "caretaker" role with me.
He keeps saying that this will be good for our relationship---I hope so. I know that my lack of stamina for activities and stuff has been a strain, so hopefully this will improve. It seems to be helping so far---I've been going through the process with a nutritionist, etc. for a year and have lost over 50 lbs. so far. Surgery April 12!
