Can you please tell me what you think i should do?

I'm 22 and my girlfriend is 21. I live alone and last night i invited her over to watch a movie. At 1am she was fast asleep on the couch. Because it was so late i let her stay the night. She lives with her parents, and her dad wasn't too happy when he found out. He knows we didn't do anything in fact she is a virgin. now here is the kicker! He Really doesn't like me ( bec i'm not asian, or bec i'm not the wealthiest man alive)! He is going to take the whole family back too China to get them away for bad influences. But i love this girl and am planing on asking her to marry me. Her dad did not like that idea (I asked). He said "MY daughter needs someone with benefits!!", but im still going to ask her. They are going to china it a month. what do you think people.
