This chick who goes to my school, quite attractive, 8/10. I rarely see her around town, but on the occasion i do, i've hooked up with her previously, now I'm trying to get her as a plate or even an LTR, I'm not sure how to approach as i don't see her in person much, yesterday thinking it would be a good idea, i messaged her on Facebook saying 'What is your number?' She hasn't replied and now I'm confused on who to go about it. i want her number so i can call her, arrange a date and get to know her in person. Is it really this hard?
