What is going on here... and what do I do?

Yeah I agree. The last 2 rounds of this with him have led me to a counselor before - think it's time to revisit.

My life with him has definitely been a roller coaster ride. I know he's got a family history of bipolar, but regardless if he wants to deal with it (in a healthy way instead of through these bouts of trying to find 'happiness' through EA's, PA's and what would be a bit of manic behavior).
Either way, I guess I need to focus on myself.

It's easier for me to get out what I want to say in writing to him than to talk to him (guess I don't need to 'see' the rejection).
I wrote to him that if he wanted to move out as he wants, then I will not stop him. He can use his next two paychecks to get the deposit ready for his apartment. I know that as he gets over the summer, he will miss out on all the summer activities we used to do (we do really well in the summer together because we get to spend time outside).

Either way - bipolar or dealing with spouse who wants a divorce, I have to focus on creating my own calming environment. And go to a counselor myself now. This too shall pass. It always does.
