I'm not sure what just happened. I was out at a bar with a friend, just hanging out, and ended up bringing a HB7 back. We were sitting at the bar, and the HB7, who was with a friend, was chatting up another guy. She ended up saying something to me which prompted conversation. We talked for a bit and after she got her drink she went back and talked to the guy from before, but her friend stayed. I chatted up her friend for a bit, half hour maybe, and then she left to go to the bathroom.

About 1-2 hours later, as I'm walking around, I spot the friend again and have a brief conversation. Shortly after engaging, HB7 comes over and joins the conversation (at the bar). Eventually she ends up saying that she owes the guy she's been talking to a drink. I tell her to give him the drink and come back here. She says ok. HB7, I, & her friend talk until close, with me and HB7 flirting and touching a lot. I agree to walk them home. As we're leaving, 2 guys attach and walk home with us. At the time, I thought the girls knew them, but it turns out they didn't. One sticks with the friend, about 20 feet in front of us, and one sticks with me and HB7. The one walking with HB7 is trying to win her over - they are talking the whole time, but I know it's not serious as she keeps checking in on me. When we get to my street, the friend turns left, and to go to my apt it's a right. I stop HB7 and let the other guy continue walking. He gets the hint. HB7 comes back with me, saying 3-4 times she wasn't going to have sex with me. I say ok, I didn't ask you to. We get back to my place and are watching TV for 10 mins or so - at which point she asks why I haven't made a move and that she doesn't feel pretty. I said that you made it clear we aren't doing anything. (I was going to eventually, just wasn't sure how long to wait). She said, I said we're not having sex, not to not make a move on me. I grabbed her, rolled over on top of her, and started making out. I started kissing her neck.. and then picked her up and carried her to my bed (we were in the living room). At this point, she says she should leave. I said ok, call your friend and make sure she's awake, and I'll walk you down. I asked her what freaked her out - she said she just broke up with her bf 3 weeks ago, and shouldn't have come home with me to begin with. She said sorry for being a tease, she should never have been here. After walking her back, she said thanks and walked away. I mentioned getting her number, she said she'd see me around.

Now, I know I messed up somewhere and that I could have sealed the deal. I'm just not sure where, dealing with the "I'm not going to have sex with you" to "why haven't you made a move" - etc. She was playing a lot of mind games. Probably had something to do with being a Pysch major.

What'd I do wrong?
