Its not about wrong or not enough. Sometimes a girl just is not attracted to you. Sometimes she's attracted but just not comfortable yet. Sometimes she doesnt want to seem to easy. From the way you described it, you pulled her for a kiss in the exact same way 3 times. Maybe this was awkward for her. Detach your ego from it. Im not one to tell you to go out with a chick to waste your time, but play around with it. Thats how you get the experience to know when a girl is just not comfortable, and when she's just wasting your time. There are many reasons for a chick not kissing you. Again, maybe she's just interested, but find out first.

Yeah I see what you're saying. Better to know than drive yourself crazy trying to figure it out.

I've just been getting friendzoned or outright rejected a lot and this time i really pushed myself to do things i wasn't comfortable with instead of being passive like i usually am. I've tried it before over the passed few months and you can definitely tell when a girl is getting creeped out. I was just delighted that this girl didn't seem to mind me pushing that envelope. The problem is that I'm getting the same result. It's frustrating.

What do you want from her?

Dude, I'm just looking to get laid lol. I could have been fancier and planned this better but i was literally just thinking "eh were doing a project, but this chick is hot, ask her for drinks, try out this escalation thing everyone talks about, and go for the close"

Literally my entire premise was just fuck it

And for somebody who overthinks a lot, it was liberating

She's teasing you cause you're letting her.

How does one not "let her"? I'm pretty much doing what most people advocate.

Part of me is really starting to believe there really is nothing to any of this stuff and it's really just a numbers game. Right place, right time, right type of person. A select few people luck out, a majority sit on these boards, lurk around for advice, and nothing comes of it. All of it driven by vague advice and tips that literally just spin people in frustration...

Some girls don't want to hook up right away. She wants a chance to get to know you and think about it a little bit and whatnot before she goes through and does anything with you. She likes you and is bringing her roommate because she doesn't want you to try and fuck her yet because she isn't ready. So basically you hAve to make her more comfortable by hanging out a few times and keep on flirting with her, and eventually she will be more receptive when you try to fuck her later. Also don't text her a lot so she has a chance to think about you and miss you. My 2 cents
