Because this morning, when my DD was being annoying (she's 11) he picked her up by her arms, moved her across the room, dropped her and smacked her bum. I was horrified.
I love(d) him very much, but this isn't acceptable is it? This isn't a difference of parenting styles. He's saying I am crazy and overprotective and being stupid.
I don't want to be one of those people who put their relationship over their children. This is not ok.
