Me [18M], She [16F] It wasn't really a relationship until we went to a summer camp 10 days ago...

So, long story short:We've met a year ago in a summer camp , she and a guy there got together but their realtionship didn't last (he was from another town). 

Me and her keep in touch, hang out from time to time, and I figured out she kinda liked me (I can read some body language). This summer camp was pretty lame and we've been together for a few days until she broke up with me saying: " she doesn't know what she wants and I want a serious relationship". 

I felt very hurt when she did this , especially because she did it with messages instead of telling me in face (she said she had a very busy day and she couldn't). I got angry then she got angry and now I don't know what to do. 

In the beginning of the conversation she sounded like she still wanted to be friends but by the end we got were very angry (no foul talking though). It's not like I can't find someone else, is just I really feel emotionally devastated. I don't have any friends to talk to although I am (used to be, now I can't even smile) a very sociable person. 

I feel that I was just some short term thing used to get rid of boredom in that lame camp and now that's over I am no longer important. Should I try to talk with her again after some time or should I break all connections?
<bot>: Me and her broke up after we've been friends for a year and together during a summer camp, I feel that I was used and don't know if I should talk to her again.
