We made out, But, Did he use me?

Okay when i was in Colombia like 2 weeks ago, i met this 16 year old guy and he seemed soo sweet at first and well yeah we kinda made out like a lot, i got to know him and everything, there was a lot of touching and making out. and now that im in the U.S again, we talked like twice since i've came back, i mean did he use me just for some making out? and every time i catch him online on MSN i like sometimes try to start a conversation with him, but it just doesn't last for that long. and i really like him a lot ! .
