There are different women and they have different needs,
so it's really hard to come up with something, but i'll try nevertheless...
Picture with both of you in nice frames / something similar you can place on the shelf and watch.
(For example, my wife's biggest wish was to see Taj Mahal, so i've bought little, mahogany miniature of this mausoleum and promised that we will travel there).
+ 10 chocolates (each different)
+ a little poem written on decorative paper.
It may be something similar to this :
"10 chocolates
each for one year...
each for something else...
First, because i love you.
Second, because you love me
Third, because there's no one like you
Fourth, because..."
And so on, and so on...
Also : make this day special.
Shave, clean, wear nice clothes.
Take a free day from the work - if possible.
Go somewhere for a little walk and - if possible - show some place and say
"and here, x years ago i finally understood that everything i ever wanted is you, nothing and no one else".
Be f*cking nice, with extra cherry on top.
When ready give your present, say something nice, like :
"i know it's not much, and you deserve more, but i couldn't think about something better because i'm thinking about YOU all the time"
If your wife is true
lady then she will appreciate it.
