Bipolar isn't synonomous to abusive.
It saddens me that you explain away his behaviour with a diagnosis, and not much else. I would not have posted bail, his actions, his repercussions, his problem. Then he still has the audacity to question the state of your finances????

No. Its time for you to smell the roses, he needs to shape up or ship out. You may feel its ok to put up with this BS, you literally signed up for it.

Your girls on the other hand did not.

I know you're struggling, having a really difficult time with this, and I'm sorry if I sound harsh, but this is definitely one of those "shatter the glass" moments, its time we call a spade a spade.
