Classic example many people here are in college im sure.

Girl in class sits next to you, you end up talking to her for a few days then what?

I threw a raging party and told her to come, but she ended up staying home with her friend for some retarded reason.

Haha, I mean, we do homework together but I can't get her to just come chill, what the hell? Shes pretty cool, were into a lot of the same stuff, but I dunno, something gives.

I was thinking about trying to freeze her out a little? In class she always likes to talk and such so I figured I would just be a little more un-responsive or not talk to her as much before class. Any other ideas?

Freeze her out of what? You haven't done anything. In order to freeze, you've got to have something there. If you play the disappointed little boy who didn't get his candy route and you're done. Continue with this "needless chatter" route and you'll functionally be her gay guy friend.

You're already her "friend" so now you need to amp up the fun factor. Perhaps a "raging party" might seem fun for you but what's in it for her? Sell the fun.

Don't be dissuaded by the guys who've read a few books on pick up. Being complimented for her looks IS "fun for her". Being recognized as attractive IS "fun for her". You need to demonstrate that you are a man and that you appreciate her. The problem with most guys is that they stop there with the compliments and then think that girls will go crazy over them. You need to keep going with your show. Figure out how to CONTROL your social interactions with her the way you see fit for the rewards that you want.

You: Hey, that's a hot looking dress on you. Sexy . . .

Her: Blah, blah, bl

You: (Cut her off) Hey, you missed a crazy party. (Then sell her the fun. Tell her specific events at the party)

Her: Really? I kinda wanted to go but, blah, blah, blah,

You: We'll have some more. Maybe in a month or two. We need some time to recover. Hey, did you hear that ______ is throwing a party next weekend?

Her: Blah, blah, blah. . .

You: Are you gonna go out once in a while or is it another renta-movie night again?

Her: Blah, blah, blah . . .

You: Ha ha ha . . . you have the cutest little excuse face. Well, I'll see ya . . .

This frame makes her feel . . ."Maybe he's interested in me."(The mystery and challenge is there) It makes her feel . . . "Shit, I'm missing out!" (You're selling her all the fun) "He's going to have a blast whether I join or not. (A more adventurous girl could grab you on any given weekend) "I could be one of those girls" (He does find me attractive right? Could it be? Maybe? I dunno)

. . . And it makes her feel as if she's in control over her decision to go. You haven't asked her for a "date" (which can trigger an automatic 'no' response from nervous girls)

Get rid of all the lame one liners out of your dialogue. "We'll go to the party and hang . . . Let's go chill out . . . Do you want to come to this party?" (This is boring and it amounts to, "Come over and we'll get drunk and I'll try to fuck you." And definitely lose the UNNECESSARY chatter. Women are comforted by bullshit. They love to chat, chat, and chat. They do this ALL THE TIME with hair dressers and their girlfriends but I doubt she's giving any of them oral sex.

Your goal isn't to comfort her. Your goal is to get her excited about you and your fun life. Sell it.
