When is the right time to ask her out?

I really like this girl but I dont know her that well, we have only talked a couple of times. She gives me glances and tries to sitt by me every once in a while but I dont know when to ask her out. Should I wait and get to know her better and talk to her more, or just ask her now?

My advice to you would be get to know her better. Try and talk to her on a more regular basis. You will then be able to see if you have things in common or if there is chemistry there. Most relationships develop out of friendships so work on that basis. As time progresses you will know when the time is right to pop the question.

Dam it. Today she was totally ignoring me. She wouldn't even look at me. I haven't done anything wrong either, I didn't even get a chance to say anything to her. Looks like I may have to pospone asking her out.
