I used to just try to ignore it and talk it over with my boyfriend or a close friends, but it's starting to spill over into the rest of our family and she's spewing lies to the very few family members I have left. She refuses to accept blame for ANY type of situation whether it's tiny or life-altering, current or long-past. She's becoming completely unmanageable and I don't know what to do.
It's more complicated than that, unfortunately. I'm the only one this person has left and if I move out, they have no way to pay the bills, eat, etc... I'm working on an escape route that won't leave her with nothing but it's going to take a while.
