Hey guys, I've got a problem and I need some feedback from you PUA's out there !
I met this girl on this ski trip organised by the greek society of my university, we talked about 2-3 times over the 3 day trip. I was introduced by a mutual friend and from there it was just casual.
After the ski trip, a few days later I added her on Facebook. I approached her the first 3 times whenever I saw her on, then I stopped to see if she would approach. Then the next day she approached me, this is when I decided to ask her out after a little chatting. I asked her if she wanted to go out in 2 days time, but she was busy, I told her no worries another time. We continued chatting for 5 mins and I said to her "think ill jet ! ps wats ur number and we'll organise som otha time to go for a coffee" she gave me it and replied "see u then

:) sweet dreams xx" which sounded positive.
That was a Tuesday night, after that I avoided fb and I messaged her on sunday morning. Don't know why, must have been the hangover but messaged her at 10am saying something like "I just woke up and I thought of you, are you busy on monday night" she then replied that "she isn't allowed out during the week, because of university".. then i replied with general convo and she didn't reply and I dont know why..
I left it at that, the next time I messaged her was on the following thursday night.. I wrote " Congratulations" and she replied "for what :/" me: "Congratulations. I was just thinking of you" and she didnt reply

btw i think shes shy she's 18 and I'm 20.. (i was trying to be cute :S) I know, dont tell me, to early !
Ok, the next week we spoke on fb once, I approached.. Then on the friday when I was driving home from university, I called her while I was stuck in traffic, and she picked up straight away, and we talked for about 5mins. (stopped because she doesn't talk while driving.
Know I'm stuck I'm thinking I need to just STOP ! As I'm doing to much ! I should have realised, but because I liked her I kinda forget the make her chase you as well, don't just call and text and approach more than what she does.
So what do I do I've avoided messaging or any other form of contact for the last week. Is it a lost cause should I just forget about her move on, I'm guessing the only way I would still have a chance is if she messaged or called or something, otherwise its over...
Would it be cool to send a message after like 2 weeks of no contact saying something like "Hey, hows it goin stranger" or just calling on a friday using the traffic as an excuse and try again. AAAAAAA ! :S
