Hello, I am at a crossroad, and have nobody to talk to about my situation. I have been with my husband 3 years, he has 4 children. One of them has in the last 9 months, brought us almost to the breaking point. She is 30, formerly self reliant, formerly married and seemingly stable. Her wife left her very suddenly last Sept, and she has basically turned into a lying, manipulative,verbally abusive terror. She claims that she has dementia, which I have experience..lost both parents to it. I, however feel 95% sure she is on meth. She is completely erratic. Won't get a job, and expects everyone to hand her money. We have helped her with thousands, which she blew on hotel rooms, saying she was on a "journey"My husband keeps bringing her home to help her, and she wigs out and says foul things. She demands money cars etc. She just stayed with us for 11 days of pure awful. We fed her and put her up in our RV she weighs 83 pounds and she is 5'3", all the food we cooked, she left rotting in bowls in the cupboards and threw food and plates with silverware in the garbage. He took her to buy a 2 thousand dollar car. As soon as she came back I saw her loading up, she then left for 24 hrs. Came back next evening all angry and nasty, and left. Next day we noticed things missing including a flat screen TV. My husband told her he was done with her, but he takes groceries to her, I am having issues with him folding and being so naive. I feel unwell around her afraid to tell hubs that I don't want her around.. sorry for the novel.
