I believe your social anxiety is coming across in your texts to these girls. They're picking up on it and it makes them feel uncomfortable and they don't know what to say. As for your idea that maybe you should be more aggressive:
NO! Bad idea. Confidence, yes.
Assertiveness, yes.
Aggression, NO!
Also, what kind of girls are you texting? Are they sweet, godly girls who love Jesus? Are they joyful and vibrant in spirit? Or are they flirtatious worldly type girls who just want to chatter about themselves? I like Willie_T's idea about meeting girls in person. Go to church functions and get involved in a youth group. They do a lot of fun things together. You'll learn to overcome your social anxiety.
I hope you do give that a try, dear. It's not good for people to be alone in the world with no real live friends. I'll be praying for you, Monnkai.
