I know I answered this question before, back in November I think. Still, that is a long haul back through the archives, and your case is very different anyway.
You got turned down by a guy for a good, honorable and valid reason. It happens to the best of us, never mind the rest of us. You now have an acute case of flaming drawers for a guy you can't have, and who shows, if I read between the lines correctly, minimal interest in you.
What the hell are you thinking! Are you actually thinking?
For God's sake, pining over some guy who you never even went out with is probably the third stupidest thing I have read all year on here, and you beat out some really stiff competition! What, exactly, is there to get over, here, your feeling of rejection? If one guy turning you down has this effect on you, you are going to have a very interesting life, in the Chinese curse sense.
It doesn't matter if you are the worlds shyest wallflower, or the type of girl who does an impromptu striptease in the middle of the Mall (note - I much prefer the second type). Stop obsessing about this one guy. Destroy your shrine to him - and I do hope it is a mental one, not a physical one.
Get yourself out there. Pick up a guy and have some fun - it isn't exactly rocket science. There are shedloads of lonely single guys out there looking for love, and even more who will take what you offer and run, after hopefully hauling your ashes to both of your satisfaction.
Find someone who really wants what you got. You are young and female. It should take you all of an hour.
Replace this guys face in your lonely fantasies with a real, warm, loving person at your side.
Wish it was as easy for the guys... sort of.
Its not that easy. Guys think women can find someone fast but its not true.
amen.
I third that.
