<human>: So I don't go out that often, but I was invited out on Saturday night to my friends birthday, we go into the nightclub and she has the vip balcony area sectioned off for her, roped off and everything and there's the waitress which also unhooks the rope an then rehooks it if you want to leave that area.

Although looking content, I could tell she was bored, so I decided to start talking to her and make her work a bit less tedious. after talking for a bit, I go forward and basically say 'I'm trying to make more friends, you seem like a really nice person, can I have your name?' 
Me thinking she wouldn't be allowed to give out info at work/with that excuse at bay anyway, I took my chances anyway- and got it, awesome I'm thinking, okay - so talk a bit more, and amusingly we share a helium balloon, then friend prompts me to kiss her (stupid idea...) 
anyway, later, I actually ask her if she gave me her name to get me off her back, and she said no, I would've just said 'go away, none of your business' 

Okay,  awesome, I made a hot new friend........

next day, find her on FB (definitely correct person, very unique name)  and message her... you can see where this is going now, can't you? 
quickly introduce myself, because  I forgot last night and;

friend request denied, message read, no reply

that was the first time, ever I've actually tried to make friends from scratch with a girl.... and it's a pretty big hit to the gut. 

I just don't understand, like, she even told me she didn't just want me off her back, it's pissed me off that  I've made such a rookie (albeit justified) and stupid error.She was awesome, really nice smile too... 

She owes me £3.80 for a vodka lemonade... lol 

Should I message her again to let her know I enjoyed speaking with her and hope she enjoyed her drink? or shall I just leave it?

Can you summarize the given text in a few sentences?
<bot>: thought I made friends with a girl for first time while in a club, fb request denied, message read and ignored, feel like a twat
