As a high school senior getting ready to leave my hometown for possibly another country or at least another coast, I'm conflicted as to what I should do about the feelings I have for a guy. 

The guy in question has rapidly become a close friend over the last 9 months and our relationship has always been a little flirty. Apparently early on (last winter) he had a thing for me, while I was completely oblivious. Fast forward to last spring, the dreaded prom season (being a fairly geeky girl, I hadn't planned on going) but nearly all of our friends were pressuring him to ask me. I ended up going solo with some friends as he never asked (which was completely fine) and our friendship wasn't affected in the slightest.

 Come summer time though, my feelings about him started to change--he is still the same ambiguously flirty friend he always was but suddenly I was falling for him, hard. Naturally I sort of started to send hints and signals, some of which he responds to, others he doesn't. At times he says and does things that myself and everyone around me can tell show he likes me, but other times we act completely platonic. I'm worried that letting him know how I feel now means that at best, he recpreicates and we have a few months of a relationship before  college interupts or I tell him how I feel and he doesn't recipreicate (maybe he's over me) and our friendship, which I highly value, dissolves. 

So what does reddit think?
<bot>: Both timing and the ambiguous nature of my friendship with a guy leaves me wondering whether its worth admitting my feelings or just supressing them.
