He's angry because you ruined his perfect little story. The OW made the choice to not contact him, not you. When it's secretive it's much easier for them to think it's their perfect world. Yeah, maybe in fantasy life.
Now you know, so it has lost some of it's appeal to him. I would stay as distant as you can right now. Be sweet and cheerful (fake it!!!) at all times. This will make him realize, maybe eventually, that it is not you, it is him.
I know it's so difficult. I'm so sorry he is such an angry person towards. This part is not your fault, at all.
HUGS.
