My dad was the same way with me when I moved back home. I could live with him as long as I chose to IF I was employed. If I was just going to [censored] around and mooch and not work, I could get out and live with the rest of the bums.
You did the right thing and for your family to talk about your wife like that is unforgiveable. My fiancee has warned me that certain members of her family might be put off by my last name Valdez but she said she'll make it clear that if they won't accept me as her husband and treat me with respect, they might as well consider themselves "written off". I told her to tell her family that the Valdez clan have been in New Mexico since the Spanish Colonial period and some members of my family, though Hispanic, are just as prejudiced against Mexicans as they are.
