So, why... don't... you just go talk to her?
Just talk to her. Is it worth a potential life time of feeling regret? Opposed to asking/talking and potentially being rejected - so you can move on.
Perhaps I should take my own advice sometimes.
Excuse me while I run through a wall and then go stare at a goat.
Then you'll be a man who stares at goats? Awesome.
But I should join you, because I would give the same advice and not take it myself. Then we could be the men who stares at goats. (I liked that movie).
