What a pathetic pair they are, and lacking in any moral fibre or values. They don't even have the guts to make a go of it, which makes me think that both of them rely on you and her husband a bit too much and you are both too useful to discard.
The pair disgust me, lower than low.
Neither of them suffered any consequenses from their despicable behaviour and no wonder really, you had the most difficult battle of your life whist at the same time trying to fight the battle of a predatory woman and a man that was hell bent on insulting you, going on at the same time.
I don't know how you did it, you must have gone to hell and back and you survived, you are stronger than you possibly know.
You are magnificent.
I do hope you find your safe space, away from him using you, cooking, cleaning, ironing , house admin and pobably a whole load of other work he created for you whilst running his buisness. Self employed people always put much of the work on partners and lawyers are well aware of this.
He knows what's going to come, you have more power than you realise, he took for granted your worth, he is going to come down to earth with a bump, I'm sure, although he may not know it yet and I also don't think you do either.
What an ungrateful man he is .........
make sure this is a lesson he fully learns.
Also, do not for 1 minute ever accept he is right, you are the one who is completely right, no letting him shout you down ever again.
Good luck
for you.
