Glad you came down to our forum. You are in good company!
What your H doesn't realize, is that you showing discontent and rocking the boat is actually a GOOD thing. If he realized that his choices are either this discomfort and saving/improving his marriage or you living numb and turning to secret external sources of comfort, he would certainly choose the former.
I am so happy that you are both in counseling, separately and together. That is excellent! I hope that your H can find forgiveness and peace soon so that you can begin working together on the root of the problem that led you to the EAs in the first place.
Please keep reading and keep posting. This is a great place to heal and grow.
