Our parenting plan allows us each a 7-day summer vacation. My ex took his trip over three of my normal weekdays. My trip would fall over two of his weekend days. Our plan does not specify weekdays/weekends. I even offered to allow him to make up the time--although I don't think I had to. Now he's saying if we go, he'll call the police and have me arrested for kidnapping. I've been overly fair allowing him to see the kids during my time but he has never taken advantage of it. I've even split my weekend after he took another vacation so he could see the kids. They are terrified the police will show up on our vacation.
