My ex has said that he would like to take DS5 to Ireland over Christmas. Ex's partner's family live there which is the reason for going. When he first mentioned it I made my feelings known that I absolutely did not want that to happen and I would never ask the same of him. When I tried to arrange annual leave today he said in front of DS that he still wants to take him. (DS actually immediately said he didn't want to go). I said that we would discuss it in private.
Last year we agreed one would have Christmas Eve / Christmas Day and then go to other parent on boxing Day and switch each year. This would be his first year of having DS on Christmas Day. He hasn't given me exact dates yet but he alluded to it being at least a week and not returning in time for boxing day.
Ex's family all live near me so if he had to stay behind he would not be alone. DS has never been to Ireland or met her family. Ex does see him regularly but I fail to see how this is a reasonable request when he will miss out on time with half his family (the ones who see him the most) over Christmas at an age when he's so excited about it. He's never taken DS away anywhere before so suggesting taking him on a plane over Christmas is a big jump.
As you can probably tell I'm really upset about this so I would really appreciate some gentle advice on this one please as I'm not sure what's reasonable and how to respond.
