I continued to pay everything on my own except his school loan. We divorced so we sold the house etc. I paid it on my own even though we split the profit
What can you do? Fighting it in court would have been miserable and would not have netted me much, if any, money anyway because the legal fee's would have made it a wash.
ETA: My name was the only one on the mortgage, even though his name was on the title. That is the law for married couples in the state I live. I would not default on the house payments because I didn't want my credit ruined. He didn't care - and wasn't working so didn't have any $$ anyway. He did leave the house. I was living in it for awhile but then found the house I would be buying when our sold so moved into that one and it sat empty for about 3mos - which I paid for.
