This is a shocking thread.
Particularly the references to other threads, which lay out a vastly worst view of your husband.
That poor boy, having that nasty, loud bullying drunken sleeze, come into his life at such a tender age.
He's had 9 years of this.
HIS behaviour is reactive to the horror of being relentlessly bullied and picked on.
And he has language difficulties?
Jesus some children don't get a break.
Him going to the school and requesting help tells us a lot.
Children are mostly loathe to reach out.
But your son would rather be in foster care than be with either of his parents.
It reads as if he feels abandoned by you too OP.
It reads as if you have stood by him being terrorised in his home since Sergeant Major returned, and tried to impose his law on the house?
The bad behaviour of your son in isolation would be dreadful, but after years of being bullied, he is clearly traumatised and is reacting to anything your husband does.
When you give birth to a child, your first loyalty is to them.
To keep them safe and protect them.
That is ahead of your husband.
Do you not realise this?
It is clear by allowing this to go on for years you have chosen your husband.
Now your son is pulling away from you both, having reached out for support.
What a pity he can't be facilitated with foster care, he at least would be safe from your husband.
You don't sound like a bad woman OP, but you sound very weak.
You have made very poor choices putting that abusive husband ahead of your child.
You may live to bitterly regret it.
Sadly, it will be your son who suffers most, trying to grow into adulthood, coming from such toxic abusive background.
If you cant and wont provide him with a safe home, help him access support from SS.
Oh and your other son is just keepingbhis head dow but will be equally traumatised by your husband.
Poor boys.
