My husband has a 17 yr old daughter who moved in with us when she was 12yrs old. I have tried my best to help her, be there when her mom isn't and help her but I know I am at the breaking point. She is cruel to me, lies about me, coniving, disrespectful, snippy even in front of her dad because he won't do anything. When I confront him he says he wasn't paying attention when I know he was. Her dad and her text when they are in the same room and won't tell me what was said. Messages erased after they are done. Her dad believes her over me even when he finds out the truth later. I feel that if I don't move out or go get some stress pills my health will suffer horribly and I can't afford that right now because I am raising a 7 month old baby. I used to be a very quiet person, reserved, but anymore I am emotional, anger built up. I think it has gone on to long. I have tried talking to him about it, but he says he will try and things never change she is not disciplined and when we are together as a family him and her are secretive like I am their kid and they the adults. it makes me feel very uncomfortable. They try to make me out a idiot and I really feel that I am not. I love him so much but is enough really enough?? Please any help on this would be greatly appreciated.
