if the house is all in ur name you can sell it. being married to her gives her the right to live there as long as you own the house....but if you own it, you can sell it. same with all the cars. I would sell it all.. move in with a friend or family, w/o getting on a lease, or buying a new place and just wait it out. it may mean you put your kids into the street but IF she plans on rising them she should be able to get a house/apt/something for them to stay in.

sucks, but good luck!
