I started my freshman year of college roughly 2 months ago. Since then, I've fucked one girl and hooked up with another 4 or 5 but I've been having trouble recently with getting flaked on. It's gotten to the point where literally 90% of the time that I make plans with a girl that I'm trying to get with, it ends up falling apart. Here's an example of what happened with a girl about a week or two ago:
We had met at a party and she flirted with me a little bit, so I flirted back a little bit. I added her on Facebook and she liked one of my pictures, so I started talking to her. I told her my computer was dying, got her number, and we texted until we fell asleep with her ending the conversation with, "We should totally hang out sometime

".
So two days after that, I bump into her and she invites me to hang out with her and some people that night because she's cooking food. I accepted and we ended up eating and playing cards with her and some of her friends. I mingled well with them and luckily, I was really good at the card game we picked, so there was a social boost there. We were touching on-and-off and at one point she was shaking her ass because a catchy song was on and I glimpsed back and she chided me with a "I saw that" with a sly grin on her face.
Afterwards, I convinced her to walk me back to my dorm, we touched on-and-off the entire way back and I ended the night by telling her that I was heading to a club and I'd be sure to let her know of all the fun she would miss out on (I invited her earlier, but she had to get up early the next day for work). 2 days later, I invited her to watch a movie with me the following Monday and she accepted.
Then Monday came along, I texted her about it, and she said that she completely forgot that she had to write a paper (lol) and that we should reschedule. I asked when was good for her and she replied with a "Idk, I'll let you know".
Needless to say, she never let me know and we haven't talked since, though oddly enough, she's been liking a bunch of stuff I put on Facebook.
All the other instances have roughly followed this same path and I know it must have something to do with me either not getting enough attraction or getting too eager but I haven't figured out how to circumvent it yet.
If anyone could help me with this, I'd be really happy.
Thank you.
