My bf of 5 yrs has a 19 year old dh and two other kids (16 & 6). I have two of my own (13 & 6). We have been together 5 yrs and we"ve been living together for 3. I want it to work, but I can't stand his oldest. She is still living at home and contributes absolutely nothing to the household by way of finances or chores. We have many issues with her lying and manipulative behaviour, the problem is my BF doesn't see it. I have thought seriously about ending the relationship as I don't think she'll ever leave home, I mean why would she? she has it made right here.
