Short backstory, kids dad and I divorced 12 years ago, kids were young.
Their dad has various issues so they don’t stay with him.
The other day his sister rang me and told me he had physically assaulted her and had been arrested.
He did this to me once and I have never told my kids about this part of him but I feel like this might be the time to do so….should the topic come up I mean (I don’t want to ram it down their throats that their dad is a scum bag of course)
His whole side of the family will believe him when he says his sister provoked him etc, etc, and I don’t want my children to think it’s ever ok.
I also don’t want to alienate my kids by putting this out in the open. I came from a family where my dad never stopped telling us everything bad out mum had done, which is probably why I have kept this from them.
