You dont text girls to build attraction.
You text girls to catch up and meet up.
Thats why the phone was invented. lol.
Anyways, you build attraction through being awsome and fun whenever she is around, showing a genuine interest in her and making a real connection.
I know, sounds hard, but is simple, natural, and common sense.
So here's my advice to you, if you have the number already, just ping her "Heyy "xyxy". maybe a little banter about your previous encounter, maybe an inside joke? watever. Then just try and see when you can meet up. This can be done within a few texts, nothing crazy. If you notice she is very chatty, good, then chat on, there are no rules, just keep in mind the concepts and go with what makes sense.
If you dont have anything in mind just ping her with a simple "Hey"
the point being, what you text doesnt matter, you already made a "real life" impression on her, she already classified you. Just play it cool, assume attraction and move things forward for a meet up.
So to illustrate my point further, just be a cool guy in person and have an attractive lifestyle/draw her in/make an effort to get to know her until she is in the bag. make sense?
basically, show her a good time, texting is merely a tool
Good luck
