1.) After you see her off.....
Be at her destination before her and hand her the biggest bouquet of flowers the world has ever seen.
Just be sitting reading a paper and casually say "Hi" as she walks by.
(I did that years ago , a girlfriend was flying to Boston to go to college , she didn't wanna go, yadda yadda....so I saw her off early morning on her 747 , jumped concorde and was waiting at JFK
)
2.) Send her a nice bouquet of flowers.
Then send her mother a shitload , as a token for giving birth to her.
3.) Buy her a teddy bear.
Then bling up the teddy bear with jewlery etc.Nice watch etc etc....maybe even an engagement ring.
Shit like this worked for me , together 18 yrs , 6 of them happy ;-)))))))
