Should I keep waiting for her?

I know it can be pretty much impossible when you have your heart set on someone, but you need to walk away. Ignore her. She knows you're interested. VERY interested. She's probably flatered, but it sounds like she has HER heart set on someone else. And if she knows you're not going anywhere she has no reason to even hang out with you. Play the field, ask other girls out. Go on casual dates - no pressure. You may meet someone else who does have time for you that you find you really like. You might also find that the first girl comes around. But the only way you might get her interested in you is if she thinks she might "loose" you. But first you gotta walk away.
