So i finally start asking her stuff. turns out she got a boyfriend, but she still came to see me. she asked me if i had a gf. I was like yea, but we on a break, hey hey i could have lied and said no. lol. anyway, she works in the mall with me. so on my lunch break i go see her and ask her if she wants something to eat? she says no thanks, i'm good! but i get her a cookie cake, and lemonade anyway. I was like, i couldn't let you go without eating. was that a good move??? she was so grateful. the next day we exchange text messages, and today. it was raining so After class i walk her to her car, and she gives me a ride to mine. sounds good,she said she had to go to work, so after a while i text her to say don't work to hard, and she never texted back. wtf? what should I do. she knows i like her, I need sum advice. help me out!!
