You are right though, if my older child (12) had seen him pushing and grabbing me, he would have been scared.
Or he may have instinctively tried to protect you and been assaulted by his dad at minimum shoving him away and at worst, much much worse.
An abusive partner who targets you in a home with a pre teen / teen son who will soon feel obliged to intervene to protect you is so unbelievably damaging to your son and so high risk.
When your son is big enough and able to square up to him, his dad will see him as a threat rather than a child.
That's why you need to leave right now.
He was in the next room. I don't know how he didn't hear 😢 hopefully he had his headphones on.
You don't know he didn't hear. Kids pretend they don't hear things when they've been conditioned to keep the peace, not place themselves in the middle of the aggression or verbal abuse, walk on eggshells. He likely goes to bed and wakes up anxious just like you.
They will be anxious all the time for as long as you stay. A constant state of fight or flight and walking on eggshells.
Living in an abusive household where one parent abuses another is abusive to the children too.
You're in danger, so are they. He hurt one child today physically to make a point. Your poor little boy doesn't just need you to be his voice, he needs you to keep him safe (along with his older brother) by removing him from this household.
Being in a refuge getting support is better for them that being taught abuse is acceptable. Because however much you say to them it isn't, as long as they see you staying with your abuser those words are entirely undermined.
My dad was pretty much an alcoholic and I'disten to him shout and argue with my mum. I's lie there, too scared to sleep. I remember several times, them shouting and me jumping up and down screaming in the middle of them.
This is why you're now in an abusive relationship. Living under the same roof as another abusive relationship is why your children will likely repeat the cycle. Break the cycle. Show them with actions, not words, that this isn't what a relationship should look like.
You're 30. Many women don't even have children at this age. You could have an entire, happy life ahead. 50+ years of happiness versus zero happiness with him. 50+ years of watching your kids be happy and healthy versus zero years of them being happy and healthy because they're living in an abusive home.
Men like him escalate, they do not get better.
Men like him hate women, that's why he now looks at you with complete and utter contempt.
This needs womens aid and police involvement.
