Background: split up with XDH some time ago, 2 kids (DD6 and DS3) who we co-parent 50-50. He has a history of not being very good at compromising, and trying to control me. When married, he was the type to ban makeup and dresses etc. Now we are co-parenting, this attempt to control continues. For example, he will have massive goes at me on the doorstep about things like putting DS in pull ups instead of pants, and thinks this is purely for him to decide. Everything's a battle and he has to win.
Anyway, new thing came to light this morning that has made me very upset and worried for my kids' safety.
XDH has a cargo bike, which is a bike with a big compartment on the front that the kids can be strapped into for transportation.
He said today during handover that he often takes them to supermarkets and leaves them in the bike outside while he goes in for a 15 minute shop where he obviously can't see them or pop outside to check. He's doing this today, but it's something he's done for a while and not anything to do with Covid. XDH claimed they can't unstrap themselves but obviously anybody else could, and at some point they'll manage.
I asked him not to do this profusely, but he was adamant that it's his call. I am terrified of anything happening to them and wish I could have kept them with me.
AIBU in being really, really unhappy about this? Is there anything I can do? I was thinking Social Services might be able to help, but I'm not sure if it's a road I want to go down. Please help. And sorry for any typos due to doing this on a phone.
