Agreed, DrM, he certainly won't see his actions as being cruel. Even when they are.
The thing about his cruelty that is most frightening to me, is that it clearly didn't start with the affair.
The idea of you, tomato, living in a design piece home you had no say in, not working, miles from family and friends, alone with a toddler, while he went off around the world showing off and having affairs, then came home and made you feel inferior to him for your insufficiently designy taste, well it chills my blood to be honest.
You would have been so isolated, so utterly dependent on him, living a life designed by him and inflicted on you.
It seems to me that you were in an emotionally abusive relationship with a man who sought to completely dominate you.
And until you found out about his affair, you still thought he was wonderful and that you were the cause of any problems you had with any of this.
Your story is like an object lesson in how smart, independent women are gradually eroded and destroyed by abusive men.
