My H is negative all the time too. And if I dare disagree with his "educated" opinion then I am just as stupid as the rest of the rabble. We could be out to dinner with someone I feel are our "best friends" and H will come home and "bash" them. It's no wonder I always felt like I was going crazy.
I know how you feel about giving up. I often still try to have a glimmer of hope but mine is pretty much gone. Like your my H needs anti depressants and a good shrink. He'll never admit it let alone get any help. He doesn't think anything is wrong with him. He thinks it's everyone else.
Hang in there and have a happy Mother's Day.
