Taken, I don't know anything about what has been happening between February and now to make a meaningful comment. Apparently, you've only just found MB, so you're just finding out about exposure, Plan A and Plan B, etc. There is nothing wrong with doing something very like "Plan A" before you got here and found a label for what you were doing. If you have been doing something like what what Plan A calls for, let us know, okay? We need to know more about what he and you have been doing, and how you've been interacting during this time. Also, I don't know if you're near your family now and whether that is a reason you might not want to go with your husband to his new job or not? Tell us all the dynamics on that, okay?
If you haven't found detailed descriptions of Plan A and Plan B, one can be found here:
http://www.marriagebuilders.com/graphic/mbi8113_ab.htmlBefore you read that thread, I strongly suggest you order the book
Surviving An Affair by Dr. Willard Harley. That short volume is the source of all the practical advice you see here on MB. When you receive it, study it well from cover to cover.
I think you need to take your situation to the "General Questions II" forum. Most of the pros out here on MB stay on GQII exclusively and you'll get far more information and good advice on that forum.
The thing to keep in mind is that others have been through precisely what you are going through now. They've salvaged their marriage and stayed here on MB to help others do the same thing. If you're willing to do the heavy lifting in your marriage while your husband recovers his mind, if you're willing to sacrifice, and if you have enough patience left, you can save your marriage and make it stronger than it was before. Are you ready to do the hard things? If you are, order that book today and begin reading threads on GQ II, then set up your own there.
