Is there anyway to get off the deed and the mortgage?

I started buying a house a few years ago with a significant other, both of our names are on the deed. We are now just roommates, for over a year, and I'd like to get out from under this but...we can't agree on anything.

About six months ago, our mortgage that was locked had to be re-mortgaged...and I was put on the spot and didn't think it out like I should have...and refinanced the mortgage through his bank and signed my namee to the mortgage.

I know I could do a quit claim on the house to get out from under it but I feel like I would be losing out....and I also realize even if I did that, I would still be on the mortgage...so that defeats my purpose too!
Is there anyway to get off the deed and the mortgage?

Another question is at the time of re-mortgaging he somehow got a loan too...for 17,000 dollars...a check that I did not have to sign for??
(But it was against the house?...(of course, I didn't see any of it!) How was that legal without my signature on the loan part?

Any advice would be appreciated.
Thanks

If two or more owners cannot agree on what to do with a piece of property they may petition the court and the court will order a sale or refinancing etc.
