<human>: I'm a 16 year old male and recently at my school there was a foreign exchange, and many students from Sweden, Finland, France and Spain came here, but only for a week. My friends and I were assigned the Finnish group, and over the course of the week we became good friends. There was one girl in the group who got on particularly well with me and we became close over the week. 

Anyway, they have been gone for a while now and while we still talk on Facebook and Skype, I find myself missing her and thinking of her a lot. We're still pretty close and I feel I'm becoming more and more attached to her, even in a not-just-friends way, but the thought that I may never see her in person again is constantly tormenting me. Anyway, I'm not sure whether I really have this strong attachment to her, or I'm just being human, and want what I can't have and fret when it goes away. I'm not sure whether I'm being ridiculous missing her this much or if this is normal. Thoughts would be appreciated, thanks.

Can you condense the text into three sentences or less?
<bot>: I met a girl from Finland on a foreign exchange and we got along well. She is gone now and I don't know if I'm being stupid or not.
