Why has my soon to be ex husband suddenly turned on the woman he had te affair with (who broke the marriage)?

Hes upset that he doesnt have two women to take care of his needs anymore. If she was the one he wouldnt have had an affair for 2 yrs, he would have left you then. He wanted to keep you for what you did for him & hold on to her for what she did for him also. Now that that life is ending he is lost because the woman he truly liked coming home to is gone & he has no one but her whose only his play toy.
