All of us who are parents on here - and those who aren't - know that children primarily learn and grow from the behaviour that is modelled to them by the adults they live with.
They have accents, personalities, mannerisms, beliefs, ways of thinking, ways of acting that are very clearly traceable back to what they have taken from their parents - we all know this.
I'm sorry, I know this will be painful, but just take a moment to imagine your beautiful, innocent DS in 18, 25, 35, 50 years' time speaking to and treating a woman who trusts and loves him in the same way as his father is speaking to and treating you now. All as a natural result of what he has learnt is the way a man should behave, from his father.
If this thought doesn't horrify and chill you to your bones, just leave things to continue exactly as they are.
Otherwise, listen to the excellent support and advice that is being offered in this thread - by people who don't know you and will almost certainly never meet you irl, but who are nevertheless showing you the love and kindness that you deserve and treating you as an important, loveable, valuable person in a way that your nasty, abusive, predatory, victim-blaming husband cannot bring himself to do
