I'm going to borrow a great quote from Starsky that encapsulates the divorce process in a perfect way:
There's a reason for the v in the proceedings. The process is painful. It isn't all cotton candy and poscicles!
Don't be a martyr in the process. Ask for what you really need for yourself and daughters in the divorce. My thinking is that your W should be the one paying child support and payments on the house until your youngest turns 18. Then you can either sell it or re-finance in your name.
This way you will have several years to catch up on savings for the re-fiance, get your credit score in order, and plan for the long-term.
