To the OP I see your conflict here with what to do/how to act. But, it's very simple the reason you even have such conflict is because deep down you WANT something from this girl. You want a kiss, you want attraction, you want sex.
This "wanting" from her is a sure sign that you won't get it, in fact you'll try to show you don't want anything in hopes of getting it! This is wrong, this causes pain, confusion, and everything that comes with wanting anything.
Take this into consideration, what if you truly could care less what she thought of you? I mean truly could give a sh*t. Becomes simple no? You'd respond with a funny neg or even ignore the text and both would send the right message to her because they'd be coming from a place of true indifference.
That's how you'd feel better about the situation and how she'd be the one in your current position wondering what to say/do/act to get your attention.
Remember, girls need to feel validated and true indifference towards them makes them act like an AFC they'll even go as far as giving you sex (their own real power against us) just for that validation. It's that pathetic behavior that gives us the upper hand.
