That really SUCKS. HE needs to pay some of this, darn it! He hasn't been deemed "insane" right?
Then he needs to give you some money!!!

For you to be left like this is ridiculous! How are you supposed to pay those bills?
So he's "mentally unstable." Who among us isn't "unstable?" Aren't we all a bit unstable? Why should HE get off scott free because he's "unstable?"
It isn't fair, darn it and I don't give a rats behind who says what. Someone needs to help you!
