PP,
My WH was initially trying to hide as much information as he could. He would only "admit" as much as I uncovered on my own.
Recently (last 2-3 weeks) he has had a "lightbulb" moment and appears to understand that I need more information. I can't live my life with his skeletons in the closet, waiting for the other shoe to drop. Each time I learn something new, I go back to square one in my recovery. As I said, he *finally* gets it, and is working on a narrative/timeline that is supposed to disclose everything to me. He is writing notes, reviewing his calendar/schedule, etc. It is taking him quite a while to put this information together for me. In fact, I'm worried that it is taking so long.
Because of our mutual concerns about how his disclosures will affect us, our MC has requested that he give me his timeline at one of our sessions. We had our last session before the holidays yesterday, and I had already figured that he wouldn't give this to me before the holidays. So now I will have to wait until our next MC in January - a month from now. I'm still on pins and needles while I wait, but in order to heal, I need to be certain that he has told me the majority of what happened.
Are you and/or your partner in IC or MC? We have a very good MC, and she is helping both of us. She is holding WH accountable, and helping him understand what I need to heal. Once I have full disclosure, I'm sure that we will delve into the marital issues that led to his affair, but that's on the back-burner for now.
Both WH and I have found this book helpful: How to Help Your Spouse Heal From Your Affair, by Linda MacDonald. It's a quick read. I bought the paperback and read it first, highlighting the parts that were the most important to me. (Trust me, I could have highlighted the entire book!) Then I gave it to WH to read. The book put into words the things that I couldn't. Also, I think it was more meaningful that it came from a "third party." It wasn't me telling him what would help me heal. It wasn't too long after that, that I began to feel like he got it, and was truly remorseful.
As others have said, go with your gut feeling. It's probably right. If there's any way that you can independently verify information, try to do that. Depending upon what information WH gives me in January, I may look into having a computer professional look at some material I fouond on our computer, just to satisfy my own concerns. But I will wait to see what WH tells me first.
I hope this info helps you, and good luck.
