husband of someone with bipolar

I believe my wife has bipolar II, as it runs in her family. he grandmother died with it, her aunt has been treated for it and her mother is being treated for it, but she thinks everybody else is crazy. She's only happy when she's shopping or lieing about getting all expense paid trips to Orlando or Las Vagas. She spends all of time with her mother who has bipolar, all they do is see's who can tell the biggest lie. Her dad drinks alot, probaly his way to cope with it. Now she wants a divorce because I have been trying to get her help, I even had to have her baker acted because I felt she was out of control. I felt guilty about doing this, but I felt I needed to get her some help, she lied her way out of it.

 We have two kids 4 and 7, she say hurtful things one minute then acts like it never happened ( such as you stupidass kids I wished I never had you ) then she put a restraining order on me, then I could'nt do anything for the kids. I'm not going to say whatelse she has done. One of her new friends might see this and tell her. ( she got rid of all her old friends when they tried to tell her she needed help Or questioned her actions. I  want to get her help but she refuses to get help, I do'nt want to baker act her again cause she will tell them another lie, so that will do no good.

I was told that she wo'nt seek help until she hits bottom. I think were there as the house is going into foreclosure, 40-50000 of unexplained depit, lost of most income her new freinds are no help not to mentioned she has stolen money from the kids.

 Has anybodyelse gone through this I need some advise on this.
