What is that movie called with the girl who's a lesbian but goes straight when she falls in love with this guy

It has a lot of dialogue in it, like a lot of fighting.

I want to say the girl is Renee Zellwiggersofijsdlk whatever but i'm not sure. She at least is a lot like her if it isn't. But yeah they meet and she's a lesbian but they end up falling in love blah blah and all this stuff. God I wish I could remember more....
