Post University/College blues going on here. Bear with me even though I'm being a bit of an asshole by pretty much posting the same FR I've already put up but I'm just desperate for some help.

After about a year of reading all this seduction stuff, towards the end of my third and final year of University I met a girl (HB9) who, to this day is sadly the closest I’ve had to a gf and probably the girl I’ve liked the most. She turned up to meetings at a society I had been part of for two years. I was vice-president and very involved in it. It basically involved social gatherings twice a week in the pub. All I did was introduce myself to the girl, ask her name and her on Fb. Sitting in the library once busy at an essay, she comes and sits next to me and just starts talking at me for an hour which seems odd considering she doesn’t really know me, she mentions that she is single. I found that we also had mutual friends so I ended up seeing her more often, having two hour long conversations with her and we became very close.

Now this is where it gets a bit embarrassing. A conversation with just me and her on films leads her to say “I’ve just got this DVD but I have no one to watch it with.” Due to being a virgin, I panicked and in socially awkward penguin style I used the excuse of having too much dissertation work to do. She then says awkwardly, “Well let me know on Fb next time you’re not busy”. Fast forward about two weeks, me and some friends go to a club and I agree I’ll meet her there. When I get there she’s a bit drunk, and with two male friends. One of which is an Alpha, talking to me about gym and creatine (bear in mind I’m a very thin guy who can’t lift much and runs a lot). He has his hands all over her, and she’s giving “help me” looks. She escapes from his grip, grabs my hand and pretty much drags me to the bar, buys me a drink, drags me to the dance floor and finally k-close. She then decides to walk home, I offer to walk home. This is where it gets worse. We get to my house, still kissing on the way back. She asks if “Can I sleep on your couch?” In a moment of idiocy, my inner AFC thought it was too good to be true, thought was she too drunk and told her to walk home. Worst decision ever.

Anyway now you’ve read it that’s the biggest mistake of my life. The next five weeks involves me awkwardly communicating with her, with her trying to avoid me and me not having to the balls to tell her I liked her even I clearly did. By the time I had told her my feelings she rejected me, probably because she was fed up of it and didn't want to hear it.

The problem is Seddit, I’m still kicking myself about this because I liked this girl a lot and we had a lot in common being on the same wavelength, and I made criticial mistakes due to being blinded by oneitus. I know I can attract a high quality girl like I did. But I think everyone happens for a reason, even the cataclysmic fuck up I just made. But I don’t know what made this girl attracted to me and how I can do it again.

The problem is, I have left Uni now and don't feel the same as I did. I feel like I've taken one step forward and two steps back and it fucking sucks. I've gone from nearly fucking a hot girl to having a mediocre social life and no job. I've gone from the independence of college/uni life to living back with the parents. The confidence I clearly embodied has gone. How do I get it back again when I'm not in many circles of friends? The friends I do have are in as hopeless a situation as me and only go to alternative clubs which tend to be a sausagefest. Does this mean I have to go clubbing on my own? :/

The worst thing is that I feel like I've wasted such an awesome opportunity that I had of: an awesome social life, awesome friends, awesome independent life, awesome girls and more.

I know I was oneitussed as hell but what I just want to get back to the awesome position I was in mentally just a couple of months ago.

TL:DR: IAmA 21 yo virgin who has improved skills dramatially but remained cockblocked by my inner AFC, met a quality girl and bottled it. Kicking myself now, how do I return to the person I was?
