[ Christmas ] Open question: Is it wrong to feel irritated because I bought all of my family's Christmas gifts and 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 she's putting her name on the label with mine. I understand that we are together, but she is not doing the same for me with her family and I said something and she said, will you help me buy my family's gifts? I think this is unfair and she also puts her name on my Christmas cards, but she does not put mine on her. I'm just a little irritated to pay for these gifts and she did not help me and she's making it look like she did it and I do not want my family to get something for her if she can not even get something for them. This is how I feel.
