What would be...

[-Adam]

My girlfriend is leaving and I wanna get her a romantic gift.

So what would you say was a romantic Gift?

[BaybeeElin]

Matching necklaces,
Both with one half of a heart. :)
So they join together like a jigsaw
If you want to go the extra extra mile, inscribe your names into them, give her your name, and you have hers ;)

Cook her dinner first, or if yur a ribbish cook take her out to a really posh resturant, and look like you made an effort.

Hand her the necklace in a really nice fancy box.

But most importantly, show her how much you LOVE HER !

I Agree with that, that sounds like a really good idea :]
and make the most of the time you have left with her. DONT WASTE IT :]
