I hope you're doing well judiz, and I'd like to add something else. When my father got really awful and my mother could no longer put off putting him into a nursing home as he was becoming a danger not just to himself but to her as well, the real guilt set in a few weeks later. Not because of putting him in the home--we really had NO option--but because SHE was enjoying herself and had a lot more freedom. My mother had pretty much been housebound for over a year and she felt horrible going out and was so hard on herself for having the slightest bit of fun.
I know this is easier said than done, but you deserve a good life too. You're doing all you can to help your husband, now it's your husband's turn to help himself. Be healthy, go out, and do things FOR YOU secure in the knowledge that you have gone above and beyond what many spouses would have done.
