Lay Report Gone Wildly Unexpected

What's up guys. In this post I'm going to describe one of the most bizarre situations I've ever found myself in. For some context, we're dealing with my hot classmate in college who I have been trying to pursue for about 3 weeks. I asked her out for drinks over text 3 weeks ago and she said she would like that, but basically wanted to wait until her schedule was freed up a bit from coaching high school soccer. Yesterday (Saturday) morning I woke up to the first text of her trying to hang out with my buddy Keegan and I. We're all in the same class and keegan and I talk about our shenanigans at the bar with Kendra often. I must have peaked her interest as she wanted to join us at the bars Saturday night. Of course, your boy Trey doesn't do group dates as that will be much more difficult to work your magic and pull back home. I decided to invite her straight over for a bottle of wine (this was particularly effective since she was telling me the other day about her visiting a winery). She sounded game and even took it a step further saying we should watch horror movies (i.e. netflix and chill?) All seemed well and we agreed to hang out at 9pm at my place. A few hours before she texts me saying she is gonna stay at home. I knew there was some underlying objection so I tried to get it out of her and had no such luck. I then called her and we talked for 20 minutes and she opened up a bit about her concerns. She heard I was a player, she saw my sexual tinder profile, she didn't want to get involved with someone in the same major. I addressed all of these concerns with humor and put her at ease. At one point she said "I'm gonna hang up and text you what I decide to do" I said "I would much prefer you tell me now." She said "Wow you're so direct." I said "Something tells me you like that." "You're so confident in yourself." "Is that so wrong" (you know the shtick boys). Eventually she agreed to come over and "have a glass of wine and watch one movie." What I'm about to describe to you is the biggest mindfuck I've ever experienced. She arrives, I greet her at my door and give her a hug, invite her in. I sit down on the couch and start asking her about something she was telling me on the phone with her roommate trying to kick her out. She stays standing for a few minutes then she joins me on the couch. We banter for awhile and I'm beginning to introduce some physical contact (hand touching, arm touching, leg touching). I notice she seems a bit nervous and has closed off body posture (taking up little space, arms crossed, leaning away from me). She even calls it out at one point I think she said something like "I barely know you." I calibrate and get her to open up by asking a lot about her, making her feel comfortable. We banter for some more time and I'm beginning to see how this might be a difficult night. This girl is constantly testing me, throwing shit at me, trying to break my frame. Basically constant negs, teases, and a few outright insults. It felt like a minute couldn't pass by without her testing me. Everytime I tried to pass her tests by humor, or even owning it and exaggerating. For example her calling me a player and asking how many girls I'm talking to I responded saying I'm actually a sweet innocent boy and she's going to turn me to the dark side. Slowly but surely things were progressing and I could tell she was really feeling me. I was constantly holding strong eye contact, smirking at her, teasing her, touching her, doing anything I can to flirt and escalate. I called it out a few times saying I'm breaking her defenses down and that I'm getting to her. The signals she gave me were so confusing. One moment she was saying I have such a nice body, strong jawline, how tall I am, general compliments. The next moment she was saying how I'm having no effect on her, she's typically not into guys like me, I'm full of myself, general negs. Eventually she brings up the wine I have sitting on the counter and we get up and I pop it open and pour us a couple glasses. We sit back down and continue bantering. I'm slowly but surely sinking my hooks in her making her laugh, blush, smile, etc. At one point she says, "hey let's watch that movie now" or something to that effect and I told her my laptop for movies is upstairs in my room. She has no hesitation and I lead her upstairs. We get in my room and I can really feel the sexual tension start to thicken. I'm turning the pressure on, getting close to her, holding long periods of seductive quiet eye contact. I'm bringing up things a bit more sexual now and at one point she looks at me with a smirk and says "we're not going to be watching movies in here are we" I laugh it off and get her to sit on my bed. I keep pressuring and looking at her lips. At one point we were quiet for about 10 seconds and she says "your eyes are super dilated" I think I said something like "oh yeah?" and then I slowly got close to her face and she puts her hand up and pushes me away. I'm unphased. I keep going and after a long pause of us staring each other down, looking at lips and back to eyes, she straight up says "alright, well I'm gonna go now this was fun." I tell her "the fun has yet to begin" and she says she has things to do tomorrow and can't stay out late (at this point it was midnight). I try to persuade her a bit more but I am unsuccessful and she starts heading downstairs. I don't let myself come across butthurt but I'm just shocked and fucking confused to be honest. I walk her to the front door, go outside with her and she leans in for a hug. I go in for the hug and when we pull apart I go in for the kiss. She immediately pulls back and playfully says "no" then starts laughing as she walks to her car. I call her such a tease and that I will win her over. At this point I am more mindfucked and baffled than I have ever been in my life. Just a second before we walked outside she had said "next time I come over I expect this house to be a bit spookier" just referencing halloween I suppose. This is the only time I can say I've gotten a girl in my room alone and it didn't get sexual. I talked to TJ on the phone afterwards and he agreed this sounds like the most confusing situation ever. Throughout the night she was constantly shit testing me, complimenting me, putting herself down in humourous ways, just changing the vibe of the interaction constantly. She was even trying to escalate the night by bringing up the wine and watching a movie together!!! After rewatching Alex's video on brats, I realized this girl might be the ultimate shit testing brat. I explained to TJ everything that happened and we could not come up with a good reason why we got to 99% close to sex and then she just dipped out. I'm not sure if I was failing too many tests but I was rather proud with how I was keeping up with her and responding in witty ways (typically I am not very quick thinking in conversations). She was telling me how confident and direct I was, but at the same time actually telling me she was trying to cut my ego down. I told her she was failing and I'm unbreakable but she replied she thinks she succeeded. So maybe she at some point decided I wasn't "dominant" or "alpha" enough for her tastes but as far as I can tell this girl was super into me and was getting invested. Is it possible she is a psychopath who gets off on teasing guys, leading them on, and rejecting them right before sex? I still genuinely don't know what to make of this situation. I didn't consider the night to be a failure; I still had a great time being with her. But her behavior really threw me for a loop. One second she seemed to be submitting to my advances, the next second trolling and me rejecting me. I am still proud of myself for getting her to come over (Thanks TJ for suggesting I call her) but this girl really confused the hell out of me last night. If you guys have any idea WTF happened, definitely chime in. Thanks guys. EDIT: Should I text her or just talk next time I see her in class? And should I bring up my confusion about what happened or just say it was a good time we should hang out again soon?
