First off, let me start by saying I spent a good five minutes deciding on which sub forum this belongs in. So hopefully this is in the right place.
Last night I was out eating dinner with my brother and his wife. I go through my first plate of food and the waitress that comes by to pick it up; I notice she's pretty cute. Asian 7. I smiled at her every time she came around and she would smile back. We all get up to leave and as we're walking out, I tell my brother and his wife to hold up. I walk up to the girl as she's getting plates from another table.
Me: "Hey, I was just about to leave, but I wanted to know your name."
Her: *Smiles* "My name is Aleisha."
Me: "Well, Aleisha, you seem like a really run person, and rather cute too. Give me your number and we'll hang out sometime."
Her: "Yeh sure."
*Exchanges number*
Me: "It was nice meeting you. I'll send you a text later."
Now this is where I need help. I went through a few back-and-forth texts and I get the impression I'm going in the wrong direction. This girl is damn cute and I would love to get to hang out with her. Here's how the texts went.
Me: "I was gonna text you earlier, but then I realised I ran out of credit

. When do you get off work?" (I ended up using a free texting service that I usually use when I run out of credit. It adds a [This is a free text etc] at the end of the message)
Her: "just got home & showered, fml that was my second day working and I already want to quit

"
Me: "Haha, I was going to ask if anyone has done the same thing as me

.
Her: "LOL, my legs are dying"
Me: "At least you weren't wearing heels. LOL. And this is my last free text for today. What is your FB, beautiful?"
Her: "truee. LOL, I don't have Facebook"
Me: "I just realised we're in a new day (more free txts

). You don't have FB? That's new. When are you free to hang out?"
Her: "no idea, they havent told me when Im working yet"
At this point, I just went to sleep and decided to deal with it tomorrow. So as I stated earlier, I think this girl is genuinely cute and I would love to get to hang out with her. How would I go about with my next few texts to turn this around? Also, if you could point out the good and bad things that I did with the initial interaction, that would be awesome.
