Boyfriends family

I don’t really like my significant others family. So does that mean he isn’t for me?

They are nice, don’t get me wrong. But I don’t exactly mesh well with them. Like they aren’t as warm as me and my family. Again still nice though. My bf’s dad curses so much, thinks he funny, says the F bomb, and gay slurs. He can hurt get on my nerves. My boyfriends sister isn’t really warm either. She’s nice but just keeps to herself and boyfriend. I’m very warm, emotionally intelligent, caring, outgoing, etc.

Idk I just wish they were a little different is all.
