IMO - Sol - you should not leave the house. In our state she could get you for abandonment. Remember she's not right right now - she might try that.
As for selling - I imagine once you start down the legal road and the L's tell her the options - her buying you out or selling and splitting, she'll sell.
I'm sorry man.
