My heart goes out to you, jlock4507. I was hospitalized for depression last May, and before I was even formally released home, my husband told me he wanted a divorce. (There must be a special place in Hell for people like that!)
We have since agreed on a separation. He moved out last weekend.
Please do not let your husband turn you into the marital scapegoat simply because you have been diagnosed with bipolar II! That's exactly what my own husband has been trying (unconsciously, I think) to do. It takes two people to make a marriage work -- or fail -- and the fact that you are struggling with an emotional disorder does not mean you are to blame for the relationship difficulties.
I am a stay/work-at-home mom, too.
Sending you hugs and warm wishes.
