Dad Refusing Sick Child

So my daughters dad and I have had 50/50 custody since July 2024. Our coparenting relationship is extremely terrible. His wife says terrible things to me and tells me I am a terrible mother. It’s to the point I’m considering getting a lawyer again. I really wanted my daughter to have a relationship with her dad, but it’s seems like it has not been going well. There’s so much that I can say, but I’m going to try and stay on topic here. Just a little background as to why I’m very on edge with coming to “agreements” I have been pregnant & sick with the flu the last few days and our daughter ran a fever shortly after. Took her to Dr to be sure and she tested positive. She’s been acting fine and fever went from 100-101 to 98-99. We operate on a court-ordered 2-2-5-5 schedule. I texted him today letting him she has been sick but she’s doing a bit better. He refuses to have her for his five days because he “can’t afford to get sick”… as if I can either? I had to take several days off of work. He tells me he pays his obligated child support so I’m able to have “flexibility with employment” when she’s sick. Like.. what? He did not ask if she could stay with me, he demanded it. He told me he will tell me his make up days at the end of the week. I told him no, there is no makeup days. You don’t get to choose when to parent and mess up the schedule even more. Am I in the wrong?
