SR, I recently went through the whole gift thing, birthday, anniversary and valentine's day. I kept it simple with a humorous non affectionate card and simple nonpersonal gifts, some chocolates she likes, an iTunes gift card and a gift card for a manicure.
If you do anything don't do anything that is personal in any way, no jewelry, lingerie, perfume, etc.
