Is there any way to recover from saying something stupid like admitting how much you like a girl too early, to put her back into the mode of trying to win you over, instead of her resting back on her heels thinking she's already won you over?

Sorry, there's not really any recovery from this. Go find other girls and forget about this one.

Alright, let me give some more context...because I don't think it's completely blown yet and I want some more opinions.

We went out for a first date, drinks at a bar, made good conversation, built good rapport and some kino...then decided to go out for food, more kino etc, eventually we started kissing in the restaurant, then on the street before we parted. I'm a good kisser and was not neglecting to kino during it, she was definitely into it and prolonged and re-initiated our kissing for some time.

Next morning, I wanted to send some kind of text to initiate flirtatious banter throughout the day...but I think my text was a mistake, I said something like how hot I was to continue where we left off...she replied instantly with "[mynickname]!!" and then I made a joke about how she could call me my fullname (since she said last night that she liked it better and would have to call me by my full name) and I would call her so-and-so name (since she said last night that she likes this other name more than her given name) and her friends would think she lied about her name to me. In retrospect I realized it was a mistake because it is presumptuous that we will be hanging out a lot more which makes it sound like I'm already won over.

She responded with something simple like, "bla bla, talk soon?" and here again I made another mistake, I said "yea, just call me anytime tonight k?", again too presumptuous, so no surprise that later she responded with, "Im going to a concert tonight..."

So, in none of my texts did I explicitly express my interest for her...but I am afraid that I conveyed the implication of neediness. When I speak to her next, I will have no room for error. Beyond conveying how much fun I've had with friends in the meantime, are there any other recommendations?

I think you're beating your self too much. You said you kissed her, sshe was into it , re initiated and so on.I think some push-pull would be handy. Other than that Id say you're actualy doing fine.

I dont know,maybe it's just me but it doesnt seem that you screwed up THAT bad. I mean yea sure you kinda did but it's nothing unfixable. Like I said , lil bit of push pull or a short freeze out should do the trick.

short freezes are magic. I would give her few days until i contact her again. That will keep her guessing what you think about that night and stuff.

thanks for advice, short freeze it is. I'm terrible at freeze outs, I need better self control...but I know they can be powerful magic. I'm gonna hold out and have as much fun possible in the meantime! Starting with tonight, had some fun at the club, hot make-out session on the dance floor, and got dates with 3 other girls lined up. All I really care about is this one girl though...
