It sounds to me as though he’s trying to spend more time with his children…that’s not necessarily a bad thing.
We have figured out that my stepchildren are loyal to whoever they are with. We have them Monday through Sunday and then their mom has them the next week. On the way to school on Monday’s they have both stated that they don’t want to go to their mother’s, but she has told us that they say they don’t want to come to their dad’s.
Maybe your children don’t want to hurt your feelings or they may not want to leave you for the weekend but do you not think that they love their father and want to see him also?
Unless the child is in danger, they need both parents to be as much involved in their lives as they can be. It may be difficult for your ex to decide months ahead of time which weeks he wants to get the children. I would suggest that unless you want to argue over petty things or there is a scheduling conflict, enjoy the extra weekends you get for yourself during the summer months. If I understand this correctly he’s really only getting the children 6 extra days a year. That’s not going to change child support amount. If you share joint custody, you need to work together and pick your battles. That’s just my opinion though.
BUT - If you want to take this back to court and fight it out, then according to the order as you put it, no he can take his weeks when he chooses but he has to let you know which weeks that will be. He is to let you know which three weeks he will take his visitations at least two months prior to the first week, 3 months prior to the 2nd week and 4 months prior to the 3rd week. A week is 7 days including one weekend so your ex including your weekend in his visitations is against the order also.
Again, just my opinion, but it’s just doesn’t seem worth going back to court or even arguing over…
