My exboyfriend and I have lived together for several years in a house I bought in my name. We also shared a joint checking account. He makes more than me, but not by much. We have several credit cards together and have mutually contributed to the fixer-upper home since we were 'making it ours'. My ex also used a portion of a personal loan that he took out to pay off 4k of my prior debt, and we have paid monthly on that loan.
Can he sue me for his contributions to the home projects over the past few years as well as the personal loan? Considering that our incomes are mingled together, I feel it would be difficult to justify what he paid versus what I paid with the exception of any outstanding debt related to home projects. He says I owe him at least 40k or he gets the house.
