I'm sorry your sitch is a mess. I'll have to hop over to Surviving and try to find you.
I did ask him why shopping had ruined his day and listened when he said, "because I suck at it." My response, "don't get so upset by it--I will love anything you and Cam get for me." I have never complained about any gift, always thanked him and said it was wonderful, etc. Now, I've had to return a few things since they were the wrong size, but never tried to make him feel bad about it. I can tell he's depressed and it seems like the littlest thing just makes him feel worse. I suppose he feels very guilty too.
I would like to date for awhile--is it possible to "date" when they move back in? I'll have to think about that for awhile since I think that's what I've been waiting for/expecting. I'm thinking that he would want to be asking me out on a date, but maybe that thinking doesn't come naturally to him.
Hang in there. I hope things get better. Happy Mom's Day! Any plans?
