My wedding is only 33 days away and we are getting in the last of the response cards and we're pretty close to the max number of guests for our budget. Then I got my cousin's response card. He was invited, along with his two daughters who are actually closer to my age and grew up with me. He responded that all 3 of them would be coming, but then added on his new girlfriend (who I met once, for 5 minutes at my grandmother's funeral) AND her two kids who I have never met. I don't want to be rude but he also did this a few years ago to my other cousin (with a different girlfriend) and he put her in the family photo and ruined that for my aunt. My mother is freaking out and doesnt want another family photo ruined by one of my cousin's random girlfriend and her kids. What do I do?!? Help!
