I have a child who lives with me from a previous marriage. My wife and I also have two children together. So, I have three in total.

We organised to get family photos taken. We had several with all five of us together, some with my wife and our two children together, some with me and the three of my children, some with just our two children, and some with just the three children. Then my wife wanted some with just her and I, and our two children together which means my other child was excluded. I didn't feel that this was fair to my other child considering it would be "all of us except them". My wife says I have really hurt her but, again, I didn't want a photo of our family with my other child excluded. I understand my other child isn't her biological child but they are still my child.

AITA?

EDIT: Maybe I didn't make the photos' content clear. I did NOT get a photo of just me and the two children I share with my wife, and not include my other child All photos with me in them had all three children in them.
