Sadly if people have no money, suing them isn’t going to get you far. If they can’t pay, it won’t go no where. It will you cost you more to sue him. I hope he just pays on it while lease lasts or court forces him to sell it in divorce

It’s really a cautionary tale to never marry people who don’t carry their own way. And never co-sign anything. It’s ok to date longer until a person is in a better shape. Dating is fine. Marrying, not so much. I know it’s too late now. But still a good lesson for others.
