When i started to read this thread, more than 1 hour ago, i could not imagine that at the end of it you would not asked her yet... please man... DO SOMETHING! Dont be SO afraid... Or you will regret later...
I myself did like you... my history is pretty like yours, but i was a pussy coward to tell her i really liked her and wished something more then friendship... so the years passed, and i had to wait some 5 years till get a girlfriend cause i had wasted that one. And she was really beautiful...
So, all in all, is better regret what you DID than what you did NOT. Im the living proof of this. JUST DO IT, man!!!
Dont stall because you're afraid of a 'no'... the 'no' only exists if you ask her. And there is a great chance she will say 'yes'... so, DO IT, MAN!!!
If you knew you would die tomorrow, or the day after tomorrow, what would you do? Ask her, and enjoy what may happens, or die like a coward? Think SERIOUSLY about this... cause you dont know which is your last day... which can be today... we dont know... Death is just at an arm of distance... just stalking us... and waiting the time for touch us... so DONT WASTE YOU TIME WITH PETTY FEARS!!!

I really wish you take my advice seriously... cause i know what is live to regret my petty fears... be more a man than i was...

And always remember... Our Lady Mary Jane can keep you cool in the moments of need! :thumbsup:
Peace, and plenty of weed for all! :jointsmile: :rasta:
