i think..

Being hurt in love sucks and it hurts like living h*** but ignoring your feelings and pushing love away because you were hurt in the past is pretty much missing life. Trust me, the last person I feel for stompped on my heart like a dead bug, but we can't condem the next person we have feelings for because we are stuck in the painfull past. Open your heart to this new person, it may open your entire life!

I'm almost certain that that's the same reason he won't ask me out. He knows I like him, I know he likes me. Take a deep breath and jump. If this person really is that amazing he or she won't hurt you.
