Has anyone ever been hated by a significant other's family?

Dude Im in the same boat as this “guy” and “girl”. My GF’s dad absolutely hates me. Ive meet him twice and talked to him collectively for 15mins. In those 15 mins he decided that Im a loser and that Im not good enough for his daughter. Wanna know the reason why Im not good enought to be his daughter? BECAUSE I DONT COME FROM “MONEY”. Dead serious. He thinks that Im a waste of space beacuse I dont have a lot of money and I provide for myself for the most part. Its like something youd see in a movie.

Im lost for ideas as well.
