Sounds like my aunt, just a bit younger. My aunt was pregnant at 16 and married by 17. She married a complete idiot who abused her, and they had four children. She finally moved back in with my grandma, but she does NOTHING. My grandma raises her kids, cooks for her and the kids, does everything for her. My aunt does nothing, but if you dont do something for her she complains. She rarely bathes, and sucks money out of the government. I could go on forever, but I'd advise you to keep doing what you're doing. If you dont your sister wont have a life. My aunt's kids have no respect, except for your youngest son. Her 16 year old has been smoking for a few years, and his 19 year old girlfriend live with them. They are allowed to do whatever, and Im almost positive he's into drugs. They have zero respect for anyone. Just keep doing what you are doing, she just needs someone to care. Good job by the way, it takes guts to do something like this when it could hurt your relationship with your family. Cant choose your family, you are stuck with them whether you like them or not.
