Of course he's angry with you. You had the absolute audacity to shatter his fantasy world. After all, he had it all. You at home, running the home, keeping the family going, being his domestic and his little wifey backup plan B, while he also had the excitement of going out to seek sex from anyone he wanted to, to boost up his ego and try to spackle over the gaping hole in his soul and morals! Hell, you didn't play your "role," in his grand and glorious life! Now he has to face the reality of having shattered his marriage vows and his family, without having the feel-good option of sneaking off to his whores!
Of COURSE he's angry with you! You pulled reality right into his rainbow-fart world!
Please read The Healing Library which is located in the upper left corner in the yellow box. Read all posts on the first few pages of this forum that have red "targets" next to them. Schedule an appointment with your doctor and have a full STD/HIV panel of tests done. And don't touch him nor let him touch you until he's done the same and the doctor's office has given you the results. In all honesty, I would suggest detaching and seeing a lawyer to find out what your rights were, should you decide that his betrayal is far too much for you to stomach.
But know that you don't have to make one decision right now, except to nurture yourself and take care of only you. Please come back often for support. We're all here for you. (((hugs)))
