Is it normal to like a girl who doesn't talk to me much?

There is nothing to lose! Nothing is impossible as long as u have good intention for her! Confidence is like a scent, women could smell it through ur action. I look like an average guy but i get womens attention by just being me. Be true to urself & she will like you.

look her in the eye, lift one eyebrow and say "sup?"

lol jk jk yeah man (or woman), totally normal.

That was how it was with me and this guy.. We had no classes together, only talked once.. But yeah ;)

Sounds like you're liking the thrill of the chase haha.. but seriously you should pursue it the worst thing she could say is "no" and in which case you take it like a man :P

what is draw something?
try to talk to her more! :)

sounds like you only know her online
or she's just not into you that way

I think maybe you like the mystery surrounding this potential girlfriend. You should ask her out.

Do you draw pictures of a penis when you communicate with her? Specifically your penis? It could help to break the ice and who knows, maybe she is a giant slut and would be happy to grab your boner right away.
