TL;DR Chatted up this girl at this bar and, a tiny hiccup aside, went splendidly. Where do I go from here?

I was a shambles. I survived what I believed to be a fight, my tooth is chipped (rendering my smile fugly, want to get that fixed ASAP) and was not in much of a mood to go and spit game. Nevertheless I was out with some pretty good friends. I paid for the cab, they agreed to buy me beer and dinner afterwards. They were mutual friends of this really cool guy I knew back in college, but anyway, to the story.

We were just having some small talk about Chinese culture (live in Shanghai) when all of a sudden I notice this cute looking girl (I'd call her a 7 or an 8) with this fedora looking like hat.

I usually just tell myself 'no, she's not going to respond well,' not to mention, I was not in the best state or mood to approach. But when she and I made eye contact, it was do or die.

I complimented her on her hat, and she responded very well. We exchanged a couple words, then told me that she was gonna hit up this bar (which I've been to, and the owner is quite nice), and invited me over.

I usually enter paralysis when it comes to things like these, trying to convince myself that it wouldn't amount to much.

But I told myself 'fuggit' and walked over to the bar. Very thankful to myself for mustering up that courage

Turns out we have a lot in common, and she was firing off lots of compliments and enthusiasm and high fives, saying I was really wise for my age and being just straight up into everything I talk about. (Once again, I should manage expectations, maybe she's just like that)

Got her WeChat (texting app in China) information, but this is where I might have fudged it. For some reason, my WeChat sometimes adds people, and sometimes it doesn't go through, so I asked her for her Facebook as well. She did give it, but mentioned that she doesn't go on it often. Might have come across as a little needy (oops), but I hope that's just a speed bump to an otherwise smooth ride

Now, the achilles heel for me is usually texting. I did mention that there's a tea place and she said she would love to go and mentioned that she would love to attend my birthday party and mentioned that her birthday is not that far off (words are cheap, so once again, I'm gonna be level headed about this)

So my question is. How do I text without being a complete dork about it (i.e.: conversations that go nowhere, telegraphing too much interest, no response, etc etc) Advice would be greatly appreciated. Thanks
