1. Stop texting. Don't get caught up in this stuff. In order to do this, you have to be serious about it. Alot of girls will give you shit for not texting them back. THATS A GOOD THING. If they weren't in to you, they wouldn't give a crap if you never responded. Instead she's sending you a big message saying "hey pay attention to me!". And the way you should respond? I'll pay attention to you when we meet up. You shouldn't get off on making a girl happy over text. You should get off on having a good time with her in person. Also, by not falling in to this "stop ignoring me" crap, you aren't falling for any tests. She might be doing that just to see if you really are busy or if she can get you into being a doting little bf with no balls.
Find hobbies, get serious about school or work, and dedicate your time to them. In your free time, enjoy being with girls. In person. Not texting. When I tell a girl I'm too busy to text, I'm being serious. I don't have alot of off time, and when I do, I'll be damned if I'm going to spend it typing up a message to her about bullshit.
Her: You're not responding fast enough!
You: I'm busy at work. If you're really bored go and buy a new dress for when we go out Friday

I'll hit you up later
That's the kind of responses I send out. It's fun and playful, reminds her of the plans to meet up, etc. And when I text that, it's because I really am busy.
2. If you're at a quiet show in an audience, use it as an excuse to constantly whisper in her ear. Lean over and whisper that she smells so good and stuff like that. Drives them crazy. If it's like a loud concert, lean over and get really close and say it just loud enough that she can hear it. You can say the same thing. If she's dancing to the music you can make a comment about how you love girls that can dance because they are fun in bed. Just go for as much escalation as you can get away with. She's obviously in to you. So act like it's completely normal and go for it.
