I've been struggling with how to respond to this thread as it hits a little close to home for me. So sorry that you are feeling bad about this.
To me, I think of a crisis in a marriage as something which puts the relationship and the trust in serious jeopardy- such a porn addiction, an affair, lying...and often the aftermath of those types of things. The way the both spouses react to the discovery of something like an addiction can cause other issues. In my case there was distrust, resentment, shame, etc which caused me to perhaps behave in ways towards my H that might have made it harder for us to attempt to move past the crisis. I m not sure if this might be what the T is looking for. I don't know.
Also as hard as it was, I knew that my H was going to be discussing me in his group therapy but I figured it was in an effort to help him with his problem. Besides, I told myself that I didn't know any of them and it was supposed to be confidential so I tried my best not to think about the fact that I was a topic of discussion. Sadly my H wasn't always kind enough to play along with my attempt to put it out of my mind by informing me of the groups opinion of me at times. Anyway.... so I do understand how hard this is.

If I have offended or upset you in any way I am terribly sorry. As I said, this topic hits pretty close to home so I am finding it hard to comment without saying too much.
