My ex husband and I separated 6+ years ago when my son was 6 and he shares time between both houses.
This summer my ex husband has told our son that he cant afford to take him away on holiday. My now husband and I are taking him abroad for a week in Greece. During this week, it turns out that my ex husband, his partner and her girls are going away for a week to Cornwall whilst we are away. My son doesn't know, yet but I know he will be upset when he finds out and will ask questions like 'why did my dad say he cant afford to go away, and then he has gone away' I have had many questions like this over the years about things (not a holiday) so pre-empting. I am upset for my son that his dad would do this when they have them later in August, so could all go together. He already feels like he is treated differently to the two girls who are older. I'm just after some advice on what you would do in this situation. Whenever I have mentioned anything to my ex in the past, I get told its none of my business what they do, which is true. I just dont think he considers how his son will feel when he finds out, which he will at some point.
