sexuality help.

I am openly bisexual. I grew up around a lot of gays on my mothers side, and my fathers side was very homophobic. When I came out i wasn't aloud home at my dads house for awhile. It was harsh but I was forced to stay with my mother. Now, I'm with a homophobic boy and he makes hurtful jokes about gays all the time. He was raised that way. we argue about it sometimes. What to do...?
