My daughter is turning 4 this year and wants to have her party at chuck e cheese, which is great! Her other parties have either been in the back yard or a park (it's in June, we had a blast last year with water balloons, sprinklers, and cooking out). I've always paid for the parties- decorations, food, games, fun, etc. This year I ask my ex if he can pay half since he's the one with the large family who is coming ( only people from my family coming is my mom and my sister and her family). 15 kids and 23 adults add up quick. He says fine but then a week later he texts me saying he can't because child support took his taxes. Trying to avoid an argument I say fine, I'll pay for all the kids and the adults can just buy their own pizza and drinks unless by June you've came up with some money to pay for a couple pizzas and ask him to estimate how many people he thinks may be able to come so I can reserve a space. His reply is "probably none due to cost". Am I wrong here for asking adults to pay for their own pizza and drinks?
