Be warned, this post is full of beta mistakes.

So I went for a drink with a girl at work (yes I know, company ink etc I'm leaving soon) and things were going pretty well, a lot of eye contact, physical contact ( had my hand on her leg etc) but I did something a bit stupid after one too many beers and told her that I was really attracted to her and started saying how sexy I think she is. She then started saying how shy she is and how she doesn't think that she's attractive and shit and doesn't make eye contact. I started talking about how important confidence is and some other bullshit including my rating of myself etc, that she agreed with.Then I did something even stupider, I asked her about this guy that she's seeing. She didn't really say much apart from that she's not really looking for anything, she has no interest in meeting his friends or family etc that kind of bullshit. He's also a 21 year old kid (we're late 20s) and he's controlling over her and wants more from it. She also mentioned that he doesn't like me because she goes for drinks with me, and told me once he started slagging off her hair or something trivial like that and she shouted "well [my name] likes it!" So anyway we left the pub went to the next place hand in hand (I know, I know, I'm not 11), danced a bit then got lost, so wandered around a bit then she suggested calling the other guy to get us, and I obviously was like "nope I don't want to meet him" so we got an Uber back to hers to smoke.

Get back to hers smoked, and I started acting like an absolute idiot. I kept picking her up and chucking her on her bed, making fun of her (these two things she responded well to), slagged off the other guy and saying I can do better etc, and when she said that we were friends I went 'I don't need any more friends' which pissed her off, then for the most unknown reason I lied and said that I had slept with the other girl at work which she was really shocked by, and kept saying her name over and over accompanied by "really?" So the retardation doesn't end here, we got into the sofa bed she'd made for me and while she was dozing off I kept shouting answers to an early morning quiz show and scratching her head to which eventually she pushed my hand off. I couldn't sleep, and went home.

A couple of days later I message her a thinly veiled and not explicit apology for acting like a kid. She didn't remember much, but remembered feeling a bit weird because she's 'been out with guys before who had no interest in actually being friends with her' etc and asked if things would be back to normal. I left it for quite a while, in which space she sent the thinking emoji before saying 'yeah I didn't think anything had changed haha'. No response.

Yeah I'm sorry you had to read this, and yes I know, abundance, oneitis etc. I have already invested too much into a girl that I haven't fucked and I'm a moron. Was my first mistake stopping the kino and natural progression and just blurting out how I felt?

My current plan is to stop messaging her asking to go out, stop orbiting immediately, start being more active with other girls etc. But the thing is, I have to work with her tomorrow (bar work) and if possible actually get a fuck in at some point (but at this point I'm not holding my breath). What is the best way I can go forward in terms of damage limitation? Is there any gold hidden among this steaming pile of shit?
