Hi guys i'm new to this art of picking up girls. i got interested after hearing about the book "The Game" and i have found it interesting so far. So i have two situations i'm stuck with and any advice would b greatly appreciated.

First girl: This girl was in my spanish class in high school and i would see her randomly around my college. I added her on facebook a couple days ago and i started talking to her about how shes been and shit like that. I asked her if she wanted to go get some ice cream or something next week and she said "Well ive been wrkin a lot lately...but idk maybe later on" and i dont know what to say next

Second girl: i meet this girl at my friends party and has it turns out there preaty good friends. During the party we took pics together and had fun we have been talking a lot and txting recently she went to colorado and i guess she got a b.f over there cause i saw it on facebook but she has yet to mention him to me. I invited her to a concert over the weekend but she said she could not go because she ahs to babysit and i said ok... and she txted me back saying sorry and that she would txt me and tell me about how her babysiting is going and i didnt txt her back. The next day she txted me and asked how i was doing nd i told her i was driving around in this town that brings back memories and she said oh ok? and i told her to come visit me during my 2 hour break next time i have one at work and she said yea and i told her i had an adventure in mind. She txted me back saying she loves adventures and that was it for the day. THe next couple days she posted on facebook saying "she loves adventures". Two days before the concert i told her to call me on sat night instead of txting me about the concert and she said ok. ON the day of the concert i didnt hear from her all day so i decided not to txt her and the concert was this past sat...so what should i do now i have yet to hear from her?

thanks in advance guys
