They are all correct. You could have used any of them - 'You never greet me first', 'You never chat first', 'You never talk first', 'You never start the conversation'.
You never write 'You don't wanna talk to me". Always, always you write 'You don't want to talk to me'.
You can say 'wanna', but you never write 'wanna'. It's ugly English to write it.
