Should i just let it go or try something different?

ok so 2 months ago i went to visit my cousin out of the country and we went out with one of her best friend to a party he was pretty nice we didn't talk that much because i really didn't know him.... when i got back home i found out he had a Facebook so i added him...the first time we ever talked was because he started the conversation and that really surprised me i thought he didn't even know who i was... anyways last night was the second time we talked and i really loved talking to him we spent all night talking i asked my cousin more about him to make sure what kind of person he was.... and she pretty much said a lot of good things about him ( she goes out with his brother so she knows him well and i know she wouldn't say something nice about him just because his her best friend i trust her) well I'm going to move down there this summer for school and ill actually be able to see him again.... the thing is that his like 5 yrs older than me and even though i don't care about age difference he does have more experience than me and im scare i dont want to make a mistake again with a guy I don't want him to just think I'm pretty i want him to like me for who i am..... i am very confident of myself and it seem to work pretty well when i talk to him.... i like him but sometimes i wonder if he thinks Im like some little girl who doesn't care and is just fooling around....... i don't know what to do!!? should i just forget about it even though i like him or should i keep talking to him and see how things turn out before i actually move and get to see him again and if i should do you guys have any advice it would really help please
