Help identifying this movie?

[Isabel]

I was watching a movie on tv and missed the beginning so I never caught what it was called.

From what I understood, it was about a blonde woman who comes from a huge Jewish family, and she is undecided about her sexuality, and meets a lesbian woman with shorter black hair. They become a couple and later in the movie, they fight because the blonde one was scared/ashamed to take her to her brother's wedding. They end up going together and the Jewish family accepts them, and the couple gets into another fight later on because the blonde one isn't satisfying the black-haired one... that's about all I caught.

No, it's not porn. lol.

I want to be able to find the movie so I can watch it from the beginning, so PLEASE tell me if you know!!!
