17 and 16yro thinking of running away

I (17F) and my girlfriend (16F) have been together for over a year. We’ve know eachother for 6 years. I have a supportive dad. Her household, regarding her mother and sister being the only people she lives with, is extremely abusive. Verbally and physically. We are looking for ways to get her out of her household and either into mine, or us both running away. We need help on how to do either of these.

If we move her in here legally things are easier but her mom is extremely against lgbtq+ and specifically me as a person. I am forbidden from being near my gf. It would be extremely difficult to move her in legally.

On the other hand, if we were to run away we have about 6k saved up and a plan to move from NY to Illinois. I’m willing to go with her if needed but would like to find safer ways to get her to live with me within the next few weeks. We cannot wait much longer with how her family has been treating her.
