Krassus: LOL bro, I've been in your EXACT situation 3x over the last 6 months. When you are being pursued by a girl she will tell you whatever you want to hear. Girls get pretty confused when the "game" is played on them and as a result they act very AFCish!! Let me tell you what happened with each:
1st girl: Met her at a party, and noticed she'd always be at all the parties after we chatted a couple times. Finally hooked up with her and FLAT OUT told her that I was only looking to have fun!! She said yeah yeah me too, don't worry. 2 weeks later, she started a crazy cycle of calling me 3x an day, trying to set up dates etc. This one particular night she had told me she was going to a guy friend's party. I told her that was totally cool because I really didn't care. I get a phone call at 3am from her and she leaves a message saying, "Hey I'm at this party and I just want to let you know, I'm not talking to any other guys and I'm only thinking of you." Finally had to stop answering my phone to give her the message. Worst part is, she lives 2 minutes away from me.
2nd girl: Met this girl through her friend, who I'm close with. We both were making heavy EC and flirting big time. She flat out asked me for my # an hour later and wanted to go out. We ended up watching movies at her friends house. This started a week long hook up every night. She was from out of town and was only visiting her best friend. I never thought anything serious could come out of this because she lived so far away. Anyway, the night before she had to leave she calls and says suddenly she can stay for 3 more days. Earlier she had explained to me how she could not stay any longer than a week because she had to take a BIG TEST!! So the night before she's leaving I go over and she's drinking. She comes up to me rubbing my **** underneath the table and pulls me in the next room. She says, "I've never felt this way about a guy ever, and I want you to be my first!!!"

I told her I was flattered but that she didn't even know me and there's no way she could like me that much!! I quickly left the house and she called me everyday for the next 3 days!! I didn't answer
3rd girl: Same scenario, told her I just wanted to hook up and she said the same. One night at a party she started crying and telling all these girls I knew how much she liked me and how she's never liked some one so quick, so much. She told me she never calls guys either. 2 days later she started calling me 3x a day. I finally had to sit her down and tell her it ain't gonna happen like that. That same girl now tells me she never wanted a relationship with me etc.
My point is, this is the time to NEXT HER!! If you don't you'll end up hurting her more. I don't know about you but I'm all for playing the game etc but I don't like stomping on peoples feelings.
