maybe your husband is manic depressive or bipolar and never got diagnosed. That could be why you never know what mood he is going to be in and he can be in an up mood for a time and then get low and angry for a time with you.

It just sounds like you have had to live your life around "his" mood swings and you end up hybernating because anything you have tried to do with him he tends to be miserable about doing.

I think that you need to look into getting involved with other people doing something you would enjoy doing. It's not healthy for you to live like a hermit unless you are at your job working that I don't think you enjoy very much either.
