Your husband is a nasty abusive bully.
Your poor son.
No wonder he has fragile mental health growing up in a highly abusive home.
Your children will know well that you are nervous.
Your husband is real scum and I would hope you really don't live to regret your choice to stay in an abusive relationship that will have had such a profound affect on that poor boy, who has challenges.
Hands shaking, couldn't eat.
His anxiety will be through the roof.
I hope you realise how vulnerable your son is.
I would get him out of that house.
I would get him to safety out of that abusive home.
He would be better in another home, at friends, where he wont be verbally and emotionally abused by his father.
You have chosen to stay and rear them in an abusive home.
Don't be surprised if he judges you harshly for putting his father first.
I would report your husband to 101.
I would contact Women's aid.
I would tell ALL family and friends that you are all bullied and abused by him and need their support.
Your sons mental health is at stake here.
