Hi Tangled... Welcome to PC.

I'm really sorry you're going through this. Yeah, what you're describing sounds like the rapid cycling and mixed states which can occur with bipolar disorder. If those terms are unfamiliar to you, I encourage you to look into them as it may give you a little further insight as to what is going on.

Whether or not to file for divorce is totally your decision, of course. However, I think the best way to look at all of this is your husband is not well. He's not doing all of this to you because he doesn't like you and is a big jerk, he is doing it because he is ill. It isn't about you, you're just the closest person to him and the one who gets the fallout, unfortunately. It may not be a bad idea for him to stay with his parents for a little while, to get himself sorted out and for you to have some space. It is unfortunate that this is happening while you also have other things going on in your life. Keep in mind that he is barely functioning for himself; he is not going to be able to be a source of support for you or your children.

Best of luck.
