How do you sort out the finances? I have a mortgage on my house,monthly payments are comparable with rental property of the same size. I lived with exp for 3 yrs in my house, he initially agreed to pay half of all bills, including mortgage, but became increasingly resentful about paying for something that was not his. He was not in a position to take out a mortgage in his name due to a patchy work history. The house was on the market the whole time he lived with me, but as is the case with many, I am in negative equity, and have been unable to sell. Was I wrong to think that him paying half was fair?
