Parents torturing mentally and physically for marriage she wont say y

I'm 21. My gf is 26. We both share same "Gotra" which is an issue for our parents. Im a dropout (because of COVID) and she has done [B.Com] and [M.Com] .I'm looking for a job and her parents won't let her do any job. She was waiting for me to get a job I asked for 1.5 to 2 years time. Both of us are serious and want to marry in future. Her parents knows about us so they forcing he to marry someone else, she said no and refused so now they torturing her mentally and physically. Cant file any complaint because that will create more problems for her. Our parents are not ready to listen. her parents straight up torturing her mentally and physically to say Yes for the forced marriage. My dad says I will prefer samaaj (Society) over you or your happiness. I am actually considering running away but again, Job is the issue. Now if we run away her parents are going to hold onto her documents (all of them). Any way we can get those back on our own without parents knowing ? What should we do?
