WHY???!!!

Why am I such a scaredy cat?! I was going to ask this guy to go to the movies or something and right before I opened my mouth, I chickened out because I thought it would be a "bad idea". I know I'm scared of rejection and all, but I thought I would be over that by now. I am incredibly shy when it comes to talking to him. AAARRRRGGGGHHHH!!!!!!!!! Why do boys have to be so complicated? I wish I knew if he at least knew that I existed or not.
