man don't beat yourself up about this, you got needy, it happens, this seems like an issue with approval seeking and most likely a lack of abundance, you simply care way way too much, your goal is not in your mind, instead you seem to be concerned about what she thinks, and if she likes you, rather then if you like her, and trying to fuck her because that is what you want, rather then what she wants (you're playing to not lose, rather then playing to win)
and yes, that last exchange was fairly needy, she brushed you off like most girls would at that point, when you have options with guys why would you be patient with a guy who doesn't move things forward? as you saw by that ''afc'' at the bar, plenty of guys will move things forward no problem, even though girls participate in group think and she humors your HAR HAR look how pathetic that guy is, type of speel, chances are if she met a guy like that alone and found him attractive, she would sleep with that guy (as likely he would move things in that direction), while being the strong ''alpha male pua'' that doesn't escalate, gets you no where fast
but don't beat yourself up over it man after all there is a possible fix to this problem, this game is not done yet, although you possibly really fucked yourself in that last exchange due to being needy about her, but it is still worth a shot

check this post, it describes why you got the friend zone, and what you have to do in the future if this situation happens again, also, go pursue other girls, and give her a good month without seeing you before you try to introduce the new you (if it is even worth it to you at that point)
