So there's this girl who goes to a prestigious school. She is a sophomore and I am a junior. I met her at a party a month ago and we went on a dinner date 2 weeks later for an hour. Anyway whenever I text her, it would take her hours or even up to 2 days to reply.
She tells me she's a very busy person. The one time we went on a date, it was one hour long. We had dinner and grabbed a soft drink and she had to "do work." She is like hb9. I asked my friend who goes to her school and he's like oh I know her, a lot of guys are after her blah blah.
I was wondering if I should continue to pursue this girl or should I just give up?

me: nov 28 11:50 pm, Haha alright...I'll take you next time if you promise not to embarrass me in front of my friends

me: dec 4, 5:00 pm, Hey crab dork! There's a party at (place where we met) tonight!
---crab dork is an inside joke----
her: dec 4, 11:14pm, Aw I think I'm staying in tonight, have fun though!
---notice the time, again! -------
me: dec 6 12:06 pm, Do you like to cheer for guys and gals doing hot hip hop dance on stage?
her: dec 7, 7:56 pm, Haha how was your partyy
---I haven't replied yet---
Anyway, notice the time of all her replies. She owns a blackberry and she definitely (I think) postpone her replies after she first read them. I know a lot of guys are after her but she still reply to my texts. So I THINK she is SLIGHTLY interested. I have no idea though. What should I do next to get this girl, or should I just give up?
Maybe I will make some bs and be like do you believe love at first sight or something lol, idk if it would work.
Advice please? THANKS!
