Have your in-laws betrayed you?

My in-laws keeped bugging for 3yrs to move together for health reasons.not terminal, but disabled. So we agreed to sell both of our homes and buy one together( @$125K each). I sold mine 1st and quickly moved in. then he couldn't sell his overpriced right away. by the time he did at a reduced$. He decides not to put anything down after he moves in. We fought for a year. I kept telling him he needs to move out. he did after a year.he will eventually loose his new house he overpaid.
