She's kind of uptight and conceited. What should I do about this girl that I'm seeing?

I've been talking to this girl for about three months. She's been great and we seem to have alot in common but we have different upbringings that sets us apart. She's not rich, neither am I but she's trying to go into marketing and I want to get into film or literature but the way she talks sometimes makes her sound a bit snobbish, when I'm not like that. If something doesn't relate to her, she'll call it ghetto. It's kind of annoying and somewhat of a turn off. Our plan from the beginning was to be friends but sometimes our feelings get in the way but as soon as that happens things come out of her mouth that make me second guess her. What should I do?
