I would like to think i have a pretty good day game at my college. During classes, i would sit next to a girl, talk to her, get her number. i got 3 numbers this week, which is pretty good id say for just classes. but its obviously not good enough, cuz when i ask them to actually hang out like a couple days later, i texted 2 of them a few hours ago and said "hey! what are you up to tonight?" to both. Girl A responded "prob doing hw lol y" id respond, "cuz i want to hang out with you" she says idk i have work to do sorry" and i say "np, i just wanna get to know you, some other time?", she says, "yea sounds good", but i dont honestly think that she actually will if i ask her another time so what do i say next time? and how long to wait etc...

the other girl, girl B responded, "yeah ill ask my friends and let you know" responding to whether she wanted to play beer pong after a few texts about snowball fights etc.. and sounding excited. then i texted her a couple hours later, "we can get you a ride if you need cuz of the blizzard", then she says "nah, not tonight, i have class in the morning. maybe another time?"

WTF, whats with all these sudden changes in mind. im in college by the way.

i wanted to say come to the party tommorow then, but trying not to sound needy, i said "no thats fine. you should come next weekend. text me if you wanna do something before then" assuming shed say something like, "oh what about tommorow" or soemthing but she didnt respond at all.

whats the deal??

Girl A may not have that much time to hang if she has a full class load and works on the side. As doing both can limit her time to hang out a lot. But I would work on building more attraction tho as she will make time to hang with you if she has enough attraction.
She is not that into you period.
Simply put your not building up enough attraction. You got comfort down, but not attraction.
