Hey guys, I'm not new to this forum, but this is the first time I've written my own post. Therefore, I think I should start with a short introduction. I'm PHtoday, I roam around this forum from time to time. I wouldn't say I'm a super experienced PUA, but my game works often. Often indeed, but not always. Normally I move on, I dont give a shit when girls dont take the bait. However, this is an exception and I am not looking to give up on this one.
Now let's get to the story:
I game with girls for some time now. Experimenting, what I'd say. I'm using different approaches on different kinds of girls, wether I like them or not. Now a few months ago I've met this girl at my friends houseparty. I would say I felt a connection, I'm not too sure about that. However, I am sure that I like this girl. I've had a nice convo with her, I thought (or am thinking) she liked me. Of course, I started texting her (didn't get her number, used facebook messaging), started a few days later after I've met her ofcourse. I thought I'd post everything of our convo, so you could judge my game. I'm more than sure that I've made some horrible mistakes.
Me: Congratulations
Her: Thanks
Her: But with what? hahaha
Me: I thought about you, which doesn't happen quite often.
Her: hahahahaha
Me: I was listening tp [artist], then I realized you was into him too. (We both like the same artist)
Her: Yea! New album on 8th of August 
Me: Yes, in fact he's gonna have a Europe tour
Her: OMG
Her: *sends some huge weird dance emotion thing
Me: The fuck?
Her: hahaha
Me: Yea, well I'm off to training. I guess I'll speak to you later
Her: Goodluck with training!
I've visited a houseparty but I couldn't stay. I came to pickup a friend there. However, it did come to my attention that she saw me there. She was standing next to a friend of mine and pointed at me. She seemed happy. I ignored that, a moment later she waved and said hi to me. Which I saw as an IOI
Some days later
Me: Does it happen often that you ignore relatives when you see them at the fair, ma'am? (Hadn't seen her, just an opener)
Her: Well, the last time I've been there was last year
Her: So I don't remember that quite well..
Me: I could've sworn I saw you yesterday. Awkward
Her: I was at home yesterday... lol
Me: So the biggest fair of the country is in town and you are being boring at home?
Her: Yup
Me: I bet you was listening to [artist], I wont blame ya
No response after that, didn't want to come across to needy after that, so I havent spoken to her for a while and was gaming other girls. Coulnd't get her out of my head, so eventually, I started again.
Me: Bitch, I've got [album which wasnt released yet of the artist] (at this point, I preferred using that artist as its a common interest and I thought it ensured me a reply.)
Her: For fucks sake, how?
Me: I can't tell everyone, too bad.
Her: Hello
Her: I'm [name]
Her: pls
Me: What are you trying to say, little one?
Again, no response to this. Now I had given her up after this. Went on gaming other girls to get over her. However it still wasn't over. I guess I liked her. I've seen her in the club some time later. She was happy to see me it seemed. I approached her, but it was a slaughtered. It went terrible. I went to shit quickly as I ran out of things to say and I stood there like an idiot before I said that I had to go to my friends and walked off.
That's like a month of 3 ago. Now a week ago or so, I met her when I was going out with some friends. As soon as she saw me, she told me in a friendly-braggy way she was going to a concert of the artist we liked. I nodded and said nice, then continued talking to a friend of hers. No interaction with her from that, because after that she walked off to other friends. Yesterday I gave another shot of talking to her via fb messenger.
Me: I just fucking realized you are going to the concert
Her: I fucking know right hahaha
Me: Are you going to [new years event at a club]
Her: ouioui
Me: Congratulations, you are nominated for the worst socially person of the week, when do you want to pick a price?
Her: hahaha
Her: I am being social with family SPAM
Me: Fair enough, you've got my permission as I can imagine that being important to you.
She read the last part, but no response.
I don't feel like giving up on her soon, however I do realize that I do come across too needy if I continue talking to her. What did I do to utterly fuck this up and what should I do after this? Should I do anything at all?
