Aww, that's so sweet! There are so many wonderful gifts you could give your girlfriend for Christmas. It's important to think about her interests and what she would truly appreciate. Maybe you could get her a piece of jewelry she has been wanting, or a special book or record she has been eyeing. You could also plan a romantic date or surprise getaway. Whatever you choose, the most important thing is to show her how much you care and that you put thought into the gift.
