I’m sorry you went through this.
I can relate in a different way - from the child’s perspective:
I remember when my dd was a toddler and she wanted to fix a toy and she headed straight to her dad who was working in the home office.
I remember being so scared at how angry i expected he would be, I didn’t even realise I had stopped breathing; I couldn’t say a word and I was paralysed with fear. I simply could not believe my eyes and ears when DH very calmly stopped and listened to her and sorted her toy then carried on working.
It just astounded me that a father could actually stop and treat his little daughter with such love and respect. It is such a strong memory because I had never seen anything like this or experienced it. My 2 year old taught me something that day, she had total belief in her dad’s love and attention at all times, and they both taught me that that is exactly how it should be.
It hit me hard realising just how far from normal my own experience with my DF had been. I wouldn’t have gone near him if he was working, the anger and aggression and absolute total lack of interest, empathy, parenting…I knew this from even before I could speak. He would have shouted at my mum, slammed doors, thrown things then given her the silent treatment if I had disturbed him.
Your relationship teaches your children things even when you think you are hiding it from them. To this day my DM thinks she protected us from DF and we should all be unaffected. The reality is we all suffer from anxiety, depression, low self esteem and it is at times crippling though you’d never know it if you saw us.
