Minor girl wants to run away with her boyfriend due to family issues.

Hello sir/ma'am, my girlfriend is 17 and wants to live in with me due to some problems she's facing at home. Her father verbally abuses and once he has tried to strangle her. Her health isn't good, she tells her parents but her parents don't take it seriously. And her mother, tells most of the work to her, and they don't care about her health. In her worst situation, they tell her to do the work. Even if she's studying, they don't let her do that and gives her household work to do. She's always been discriminated as her elder sister is good in studies and younger brother is the only boy child of her family. Her family has implied a lot of restrictions on her, she can't talk with anyone, can't keep social media, she even can't attend any friend's birthday. She is in 11th and preparing for neet. But her parents are also not allowing her to join any institute for studying. (The is no financial problems). she can't do anything. She feels like suffocating. Father abuses or does something on daily basis that makes her feel worse, uses bad words like "Randi" and "behen ki Lodi" to refer her. Even her mom thinks the same when she uses her mobile, like she's talking with someone. They all have suspicious eyes on her all the time. Her elder sister also keeps saying some things and calls her "characterless", and treats her like she is an inferior. She doesn't wish to live with her family anymore. There are alot of things to add, but I'd stop here. We're planning to run away, get help from women helpline and talk to her parents on call before leaving and telling them everything. But we don't know the consequences, so wanted to ask what if they file FIR against me or both of us? I have her consent, and I know I can take care of her. If anyone helps, that would be great. Thank you.
