My ex husband is taking our two kids (9 and 11) abroad for the first time next week. They are going to Paris. I know this because the kids told me. I have asked their dad to give me their flight details-I'm not asking for their full itinerary I just want to know when they're in the air and what city they are in. I've asked politely several times but am getting no response at all. Our separation agreement states we need to give written info on travel details when going abroad but he seems to be ignoring this. I don't normally get into on where they are when they're away, but this is first time they've been abroad and feels different. AIBU?
