You said you would like to try. You did. It did not work. Moving right along, find another girl that would like to date YOU- because that one did not.
You act like you like her to get in her pants (:
As a girl myself I think it should be the girl's responsibilty to respond but not to hold the conversation.
Tell her you'll text her when you get less busy. Do it politely.
go outside
just say thanks honey/ darling/ babe.
Probably through getting annoyed.
Maybe she is too nervous to even call you.
You answer his question or not as you wish.
Just say thank you.
When a girl told me that she is pregnant
Playing hard to get.
Don't be distracted. Unless the person has talked to you, you don't have to respond to her advances. Talk to the girl you like so you can at least start working on a relationship.
