How do I get this girl to like me?

I just moved to Florida from Illinois last week. There is this girl that I like she is more of a redneck and I'm more of a city boy. We have texted a few times but barely. So were going to the movies next week but only as friends cuz she says she wants to get to know me more. But we are going with my cousin who is one of her friends and this guy she likes. But I need help to get this girl to like me any tips??
