<human>: Provide a brief overview of the text.

Let me explain further. I'm a long time lurker, first time poster. This clearly sounds like one of those "omg i'm in luv wit my bestie halp plz" posts, but there's more to it than that. 

We met almost 4 years ago. He's from Spain and I'm from the US. He was studying at my high school. We clicked instantly and were best friends for the whole year he was there. We spent all of our free time together. Back then, we really were just friends. After he left, we've been keeping in touch. Now, I'm studying in Spain, but in a completely different area. We got to meet up for a weekend, though, and it was the best. The first time I've seen him since he left. That little time that we spent together though made me so ridiculously happy. I can't stop thinking about how happy he makes me. Now, I'm back in my part of Spain and I won't see him again for probably another year or so.

If I were to tell him that I think I love him, I am sure it would immediately ruin our friendship. We only keep in touch through social media/Skype and it'd be so easy for the friendship to end. On the other hand, he's all I think about. 

Maybe I'm overthinking this and am going to get downvoted to hell. Anyways, thanks.
<bot>: I think I'm in love with my best friend but we don't live remotely close to each other and I am concerned about losing him as a friend as I don't have a great track history with this sort of thing.
