Being forced to sell or refinance!

my ex boy friend helped me out when i was buying my first house by co signing for me since my credit did not make it alone... 3 years later he remarried and a few months ago filed a complaint against me based on me "not keeping" my deal and requesting that i turn over the house to him for a. monies he at one point or another gave me (he did help me out later financially since i was broke from the purchase of the real estate property) and b. to remove himself from any liability having to do with me. i agreed to work things out and now his attorneys are sending me an agreement wherein i have 60 days to find refinancing and another 60 days to close, and if i cannot refinince within thatntime frame that i put the property for an agreed listing price. i am a nervous wreck! i can't sleep over this! i lost my job shortly after i purchased that property so i moved out of it and rented it... i haven't found a job and my credit is still not good enough to be approved! the house thank goodness has been paying itself since i've worked at maintaining tenants... i dont know where to start with trying to see if i can qualify for refinance.... i see that the best decision would be to sell it, but i have spent so much time and effort in that property in renting it and finding tenants every year and dealing with repairs etc... i dont think it's fair that now that my ex wants his name out i have to sell... on top of it he is claiming the monies he gave me to be paid to him from the refinance or the sale... i just feel so pressured into this. and i got an attorney who is telling me that it's the only solution... any thoughts or suggestions i would appreciate... :(
