My FIL and his GF have been together for 15 years. They have a toxic relationship, however, she convinced my FIL to sell his home and lie saying she would add him to her mortgage on her new home, which she did not. He is on disability and has had 12 back surgeries. He's very manipulative and tells my husband he will kill himself. Now, he is staying with us. My husband didn't ask me how I felt about it. His own sister won't allow him to move in. This is extremely stressful as we are just recovering from marital problems. We have been married almost 9 years, and we have 4 children. He tells my husband he has 4 dollars in his account and makes us try to feel bad when we don't have extra. Then, he drives around all day smoking weed. I told my husband this can't be permanent. I will leave. Stressed, please offer advise thanks.
