KEJ,
Welcome to MB. I am sure you are going to receive a lot of advice. Have you and your H considered getting Harleys Surviving an Affair? Some of your questions are answered there. I'll offer you my take on this and I am sure you will receive a lot more.
First, your H doesn't get it yet. You don't "get over" a betrayal like this, you work through it.
That means he needs to answer your questions about the affair. It means he needs to be honest with you at all times. It means he needs to give you time to grieve and heal. So he is wrong in his approach and he is very typical of many WS.
The reason he stated
but my husband felt that it was soul destroying for him to see me express my hurt.
Is because he does not want to face what he did and that is hurt you deeply. If he won't face that you won't really have recovery or be able to rebuild the marriage. He needs to be going with you to the counselor.
Ok, here a few things for you to consider. In my opinion you should NEVER forget this betrayal. And he should not either. Forgive, yes in your time you should if you feel it is warrented for your mental health and the health of the marriage, but forget??? NEVER. Here is why.
This event is an opportunity for both of you to learn about each other and yourselves. You cannot learn if you forget the event. Your questions and his answers should be directed toward learning so that each of you can make better marriage partners. His affair was entirely his choice, but the state of the marriage is something you both contributed to, so address that. He needs to address his boundaries and why he felt it was acceptable to have the affair, and why he valued himself so little as to become a liar and a cheat.
I hope you two have read Harley's four rules for a good marriage. I also hope you have read about his two polices of radical honesty and joint agreement.
There is much more to say. As you know this is a complex subject, but I'll stop for now and I am sure others will chime in.
Your H needs to contribute a lot more than "get over it and move on" and then shrinking from the shrink because your pain hurts his soul.
Hope something I have said is of help.
God Bless
