I have nothing to compare to, but our M was very dysfunctional prior to dday, in fact for most of the M. FWW was not happy, closed herself off from me, projected her anger on to me, blamed me for her unhappiness.
We were able to R because FWW decided that she wanted our M to work. She did the IC and reading, identified, owned and worked or replacing her issues with healthier alternatives.
As for R, I think it is too early for you to be looking at that. Before working on the M problems, your WH needs to figure out why he wanted someone to make him feel wanted when he felt low? Why did he need external validation? Why was it OK for him to cheat and betray you for the attention rather than separating or D-ing you first? How was he able to lie to you? Why did he not talk with you about these things, insist that you both go to MC? These are the things he needs to identify, own, and address before he will be ready to work on the M with you.
Meanwhile you need to heal and get to a point of acceptance of his A. You need to feel safe in the relationship, see that he is doing the things listed above, and sustaining the efort. It would also be a good time for you to explore, prehaps with your own IC, why you tolerated not having sex for 6 months? Why you tolerated a relationship where the two fo you did not talk. Why did you put him down in front fo the kids? did you try to communicate better, learn better techniques, insist on MC?
Unless the two of you are able to work through these personal issues, it will be hard to work together effectively on the relationship issues.
I believe in IC, but it is important to find one who is competent and a good fit. Nearly 50% of counselors are below average in effectivness, so you do need to shop around.
Books can also help. Have the two of you read Not Just Friends by Glass or Sexual Detours by Hines, and discussed how they apply to his A and your M?
