I think you pushed the girl into a loop of rejection, sorry cant find the right words to describe it.

Me: You know, we never found out each other's favorite [Band name] song
Her: Haha who's this xD
At this point, I would have realized that she doesnt remember me and made it easy for her. You're already starting out with confirmation that she is not that interested, so I won't push the mysterious, cocky stuff.

Me: [Name], the handsome guy you met at [Bar] this weekend
Her: How could I forget?! Mind blank. Matt's mate right?
Thats what happens when you see the girl doesnt remember you but chose to be vague. Now, its awkward that she remembered another guy from the weekend over you.

Her: My apologies, must of had a few more drinks than what I first thought xD So, favorite song then?
At this point, you shouldve just said it. She's not that interested, and you're pushing her to think on something.
Quote:
Her: Alrighty then xD What's your last name?
Quote:
Me: Do you need my social security number too?
You're being difficult, when she the fuse is already short. I get you're being playful, but there are other ways to do it.
Quote:
Me: I'll be in [Neighborhood] on Tuesday, let's meet up at [Bar]. If you're lucky you'll get my PIN number too
Now you're suggesting a meetup, when you were for the most the 2nd guy she wanted to text her.
Quote:
Her: Add me [Facebook link]
Me: We'll see how Tuesday goes
Difficult again. She cant remember you, isnt ready to go out. She wants to creep your fb and see if you're a cool guy.
Quote:
Her: I don't know who you are!

[Yet she remembered me earlier]
No she didnt. She acted like she did.
I'm all for using texts to set up meetups, but you gotta realize where you are with the girl. If you're first text had gotten an enthusiastic response and callback so you knew she was happy you texted her and she remembered you, sure go for the meetup. If you see she's not really remembering you, you gotta build your shit again. I mean, she's telling you she doesnt remember you, do you think she'd really go out with someone she cant even remember?
