I'm sorry you have to endure his venom :-( That's not fair or right, but neither is the A. Expect it and just know he's miserable with himself and your the one he's blaming for HIM feeling like crap about HIMself. He's thinking "oh, she thinks she's so superior to me, I'd better knock her down a few notches to make me feel better about myself". Believe me, try and learn to let it roll like water off a duck's back. If he doesn't get a rise or a response (as his reward), it won't be worth doing it at all in the long run for him. Stay strong. You sound like a strong person and a GOOD MOM.
