AIBU as I feel my mind is slightly blown.
We are Tier 4. Ex is Tier 2 but allowed to have DCs as shares custody although we are resident parents.
Before they went, Ex gave me an absolute grilling about where we had been, who with, any symptoms etc. Bit much since I would rather just keep the DCs over the whole of Christmas and was only doing this so he got to spend time with them but, nonetheless, I understood the paranoia at the moment so answered all the questions as politely as possible.
Now I find out that for the past 2 days he's been taking them to work with him at an office where there are at least 5 or 6 adults in the building and they've been in a room doing work for money with a child from Tier 2 who is another worker's kid. So not only are my kids "working" when this should be their holidays and they could have stayed with me having fun...they are mixing. Indoors. With a different tier child that isn't in their school bubble. Yet ex had the audacity to grill me.
Mind blown. What do I do?
