Unfortunately, the lender is not bound by any agreement between you and your former girlfriend. Even if you deeded your 50% ownership to someone else, you would still be responsible under the promissory note to the lender. The only things to do are to approach the lender to settle the problem, force a sale of the home (if it has not been sold or foreclosed) and work to rehabilitate your credit.
