[ Christmas ] Open question: Is it wrong to feel angry at having bought Christmas gifts for all my family and that my girlfriend wants to put her name on the labels with mine?

I received gifts for my family and she did not help pay for any of them and put her name on the etiquette with mine. I understand that we are together but she does not do the same for me for her family and I have something and she told me that you will help me to buy gifts to my family ? I feel it's unfair and she also inscribes her name on my Christmas cards, but not mine on hers. I'm just a little irritated to pay for these gifts. She did not help me and gives the impression that she did it. I do not want my family to bring her something if she can not even give them something. That's what I feel.
