Is AUTHOR wrong in the post ? POST : My (M23) gf of four years (F22) and I are still living at home (we both go to university in my town, she lives in a city an hour away). I have no problems at home, but my gf's family is quite disfunctional. Her dad is a borderline alcoholic and im not sure about her mom, but from what my gf tells me, she has something like BPD, they are constantly fighting.  My gf has previously asked them if she could move in with friends, but the won't let her move out.

Now the thing is, I've considered moving out as well to be more independent, so right now I'm considering renting a flat and asking my gf to move in with me. Even if her parents don't want to let her go, they can only exert financial pressure, so if I take that away, what can they do? She could technically even sue them for housing/food/study costs, but if she doesn't want to, I could cover it for her until we're both out of university. 

Still, that would basically mean starting a fight with her family and I'm not sure if it's the right thing to do. Also, I wonder if this would put too much pressure on her/make her feel indebted. I am serious about this relationship and I'm not afraid to take responsibility, but I also don't want her to feel like she owes me. WIBTA if I offer her to move in with me?
