Just dont be like all the other guys. Everyone starts a conversation the same way and it's boring.
Either you find more interesting approach or go to the point directly i.e: Going to "X" place to do "Y" and take a look around later, join me, i need someone to pay me something to eat in between.
My english sucks, but i'm sure you got it.
Get out of the pattern, if shes hot theres probably +30 guys texting her the same bullshit you did.
If she accept, go with no intentions of kissing her or anything. Pretend she is ugly or that she's a friend from years that you would never date, and focus on the things you want to do, and not 100% on her. This will make you be yourself and prevent you from acting like a needy pussy slave, girls are tired of this type of guys.
