she sounds awful, i'm so sorry not sure how serious you are with your bf but crappy in-laws would be a nightmare! i've had boyfriends whose parents i didn't love (in one case, i thought they were too controlling/involved in every little detail of his life, and another set was just mean and kicked him out of their house as soon as he turned 18, when he was such a good kid...)- but nothing like that (alcoholism, sleeping on the couch, etc.).

my current bf's family is amazing! they're funny and smart and NORMAL. i really like their little family unit- my extended family is HUGE (i have over 20 first cousins) and they're a loud and hilarious bunch, and i'm totally the introvert of the family. i love my family and the side they bring out in me, but my bf's family is so much smaller and quieter, so i really like having that different experience of hanging out with them as well. if they became my in-laws, i'd be thrilled!
