I've been lurking here for a year or two and I've recently got upset enough with myself to try to change. I'm a 21 year old virgin who has had plenty of chances with women but somehow I always mess it up. After realizing what I was doing wasn't working I began I work out a lot to where people notice it, I hang out with more people and generally have more fun. After all this change and convincing myself I would stop being a pussy I still managed to do the shit I knew I would loathe myself for if I did again.

I'm in a group project for my speech class and I get hella vibes from this hb7. Everyone else in the group doesn't seem to care about the project except for her so I figured being enthused about it would be the best way to get with this girl. Building more attraction wasn't even necessary honestly this girl was giving me so many signs she might as well have jumped on me. I figured all I would have to do was get her alone and the new me would take care of the rest.

Fast forward to about 2 hours ago and I'm meeting up with this girl in her house all alone, she's wearing some skimpy little dress. I get there and we start to work on the project, small talk here and there with her so close to me our arms are touching. I keep her laughing and eventually I ask her about this guy that keeps calling and if it's her boyfriend (I saw her with him in a lot of her Fb photos so I wanted to know), but she says no he's gay and they're just friends. Time was running out and I still had done nothing except for the lightest of Kino, we were almost finished. I thought of like 10 different things to say to escalate it but none of them felt right and as soon as I'm about to go for it, her aunt walks in and I start to realize how much time I wasted and begin to sink inside. We finish up really quick and it's over like that. We say our goodbyes with her being her usual excited self and giving me a hug. Meanwhile the same thought keeps running through my head. "YOU WERE AT THIS GIRLS HOUSE ALL ALONE FOR 2 HOURS AND YOU DID NOTHING"

I feel like absolute shit and have been wallowing in my thoughts, chain smoking cigarettes since I got home

The worst part is I do this kind of shit everytime, and even after all this improvement as well as acknowledging what's stopping me and deciding to do it differently, I still manage to fuck it up with opportunity hanging in my face

This was mostly to vent because I've seen similar stories, but I also wanted to ask is if you guys think it's over with this girl. Will the fact that she brought me to her house and I never made a move send whatever attraction she had for me in the shitter, or is it still worth trying to get her to grab coffee with me tomorrow or after the presentation?

Either way I haven't felt this shitty in years, I don't know what to do right now I honestly just want to give up and accept that I'm never gonna have the balls to do what it takes.

TL;DR I'm a pussy and no matter how much I improve myself as a man, I can't seem to be able to escalate a conversation.

Edit: thanks for all the advice guys, you all are right and I should stop beating myself up over this and just move on. I'm really disappointed with myself but you live you learn
