AITA for telling a kid their mom doesn’t make the rules?

I agree they should set rules for their children but is it ok for her to police what goes on at dad’s house when he’s a totally capable responsible parent? Additionally these rules are JUST for me. I do know the kids share food and drinks and kiss their friends and mom has always thought it was cute. Also she told them they should be wearing a mask around me (even though I’ve been fully vaccinated since before I met them) but she consistently is taking them to their friends houses, extra curricular activities, and even threw a party during the height of the pandemic when everything was closed and vaccines weren’t out and no one wore a mask there either. So it just feels targeted towards me is all
