Should i be a brave loser n text/call or should i be a loser n not give in to my yearnings?

i feel like such a loser. Im hot, dammit. Ok so i went to a basketball camp to help out ma dad wit administration, im young 17 n the campers were all around my age. But one guy joined the line, n i got a wee bit too excited caz he was...in short...lovely. So, my hormones went a little crazy wen he sat infront me to sigh up. My hands trembled at my lap top like a retard. Such a retard. N he noticed. Of course i was too mortified to flirt. but he was totally awesome about about it. Throughout the week, we encountered each other n it was always friendly banter. The camp ended and nuthin developed. I kno, im a retard. He obviously wasnt interested caz i guess i give off a best pal vibe or sum such crap. So i may have stole his num from the database i wrote it on, n felt braver to text him. He texted back, n was a bit amused. I didnt profess my undyin love but i wasnt shameless either. he didt reply after the second. so i left it alone..it has been two months n im still hung up on this who hasnt texted back. N i feel like such a loser. Im not brave enought to call. It took all the i had to text in the first place n i was pressured into it. My heart cant take much more rejection. But here i am, still thinkin about this.... who has ruined me for all other men. now everyone i see i compare to him. i am such a loser. should i text for closure, should i text to make him want me. what do i do. N this is a new low for me....such a loser..help!
