Take her along to the hospital when you have your open heart surgery, that way she see first hand that you've got one 
Listen to Gypsy! she is your only hope....
im no romeo but....
flowers and cook her (a nice dinner)a collaboration for your favorite immigrant. ;-)
!!!
Open your heart man 
Present for girlfriend of one month?
Must show you understand females and how they are different to blokes
Must show you know what ladies really need
Not too expensive (short relationship so far)
Something that reflects how long you have been together
... tampons.
Give her a Birthday cake.
Don't worry, she won't get fat, wedding cake does that .
Here's another thought; Take her to the beach to watch a bit of your favorite hobby, then out to get a bite to eat Might have an opportunity to answer some questions, and convert her to a long term fan......
Gizmo and the Gypsy gave ya a good idea with the flowers too. Do both, it'll be good for both of you.
Flowers = not good.
Over time you can't win. You do it and they take'em, just that.
You skip once and ** accumulates...
I have mates that have been stuck in that loop for years... not good.
Bonus sex maybe? That usually get reciprocated the next day... 
Reading all these suggestions I would just dump her because she sounds too high maintenance.
I hope that helps.
I'm puzzled, I thought it would have been obvious, but nobody's mentioned it.
I'm sure she'd just love a new sail!
What ever you do dont buy her a million dollar house a diamond wedding ring jewlery flowers car give her kids and put food on the table every week Pay for electricity water rates.
because......
She will still winge.
Anyways i have been pretty creatively eccentric when dating I allways choose rather than a present to take part in some for of activity.
For instance we went iceskating.. Never been there before but in all honesty we both had a ball for her birthday. Think the trick is because you have been only going out short term jewlery and stuff is off the cards. an activity would benifit you both and its good teambuilding.
another suggestion is would say would be take her hot air ballooning. ( this is one that i would like to do one year)
ok, forget the half mast.we need to know how much like her to get a gauge. go on, you can tell me, mums the word.
rate from 1 to 10
