Alright guys, I'm new to using PUA forums, but I have studied 'Game' for a while and have enjoyed some success out of it, however I definitely feel rusty as I've had my eye off the ball the last year and a half due to a couple of serious girlfriends. I'm back in there now though, and my most recent success seems as if it may be slipping away, please help.

Anyway, here's the deal. I picked up a girl on a bus a few weeks back, she was 19, cute, slim, and had braces (I now what you're thinking, but seriously, she's hot, this was only a minor, or you could say 'temporary' blip). I just got chatting to her, and we ended up getting off at the same stop so we exchanged names and I inevitably went and found her on facebook, added her, of which she responded with a message and the rest is history.
I met her for drink last weekend and it went really well, I've never really had a bad date as I'm confident with my communication skills, and I know how to interest someone with conversation. I ran 'the cube' on her which she loved and then proceeded to seduce her by telling what I would do to her in the bedroom. This was in response to her telling me she had only slept with 3 men, 2 of which were long term BF's and the other was a one night stand which she said she hated. I really laid it on thick and she was literally quivering at her legs an biting her lip, I managed to get her back to my place, introduced her to my housemates then took her upstairs. I gave her massage and then pounced on her, she was getting really into it until her Mum rang and she had to lie and say she was still in the pub. This sort of killed the mood, so I called her a cab and she went home.
Second date again went really well, however I picked up that she'd come out of a relationship recently and had some issues, these turned out to be that she was on anti depressants and that she had cut herself :/ Call me weird, but I kinda like being the knight in shining armour so I kinda liked this situation. She went on to explain that she's definitely not looking for a relationship yet, but enjoys what we're doing but wants to go slow. I ran the 'bite' routine on her, and we enjoyed biting each other for a bit then I walked her home, kiss closed her and said good night. Since then we've been sending flirty messages, and she seemed keen, I asked her if she wanted to go out for dinner Friday but she'd been out with her Dad for her Bday all day, she apologised and suggested maybe next weekend?
The following night I met her and her friends out for her birthday, with some of my friends. Now I made sure I didn't seem desperate, I didn't stick with her all night, I met her in 1 bar, then left with my friends and met her at a club later. We were all over each other all night in the club and everything seemed sweet. Now here is my fatal error. As I was leaving I saw her dancing with another guy, so rather than just leave I went over, grabbed her and said something along the lines of "what you doing, I'm not putting up with shit like this" I can't actually remember as I was hammered (i know, mistake) and she'd sent me some messages I saw when I got in asking me why I had done that and what was my problem. I had jus responded trying to get her round and she ignored me.
Then next day, I messaged her on FB (thats what we always use as she never has credit) no response so in the afternoon I called her to explain things, and then I just text her. I'd said I was sorry, and that I didn't like the fact she seemed close with another guy after being with me all night, and said I'm sorry for anything bad I said, and that I'd make it up to her. She responded, saying it ok, it was just stupid and she was really drunk, then said she can kinda do what she likes, no offence but was nice to see you. I messaged back saying I know she can do what she wants, and that im not offended. And her final response to me was that shes not in the best place right now (anti depressants remember) and doesn't need anyone elses shit right now. But then went on to say it was fun and her friends liked me.
I responded to that saying not to worry and that I won't be giving her any of my shit as I wouldnt want to stress her out, and that I'm happy just doing what we've been doing. I've yet to hear anything back, although I've not contacted her again as I thought I'd let things settle for a bit. I'll be honest, I wanna bang this girl, and she seemed like she'd be up for some new things so it would have been a sweet casual thing to have going on, So anybody got any advice on how to play this? As at the moment, all I'm thinking is leave it till the weekend then send a cheeky message, asking how she is, and whether she fancies going out for a drink at the weekend?

First off man you got a serious case of oneitis, if you were gaming other girls and talking to other girls you wouldn't even be writing this long post about her, second you messed up bad the best you can do is freeze her out and eventually reestablish contact after a while(a couple of months) assuming that she doesn't contact you first and third this girl sounds like a big fixer upper which is NOT what you want in a girl these girls are usually not stable and the littelest things will set them off they are girls I'd only have for a one night stand if that. Last thing man don't be a "knight in shining armor" I did that in high school rarely got laid and got used a lot it sucked
