Heh, I have the same family situation kind of (ISFJ mom and INTJ dad). My mom literally goes out like once every six months with her one friend, and basically watches a whole shit ton of movies all the time. My dad is really good to her though.
If you want to get her out of the house, I would suggest just asking her to sign up for some sort of activity with you. Dress it up like a chance to spend time together outside of the house, and then quietly push her to make some friends there.
