First of all, you're not hopeless, but I'm so glad you found this website. I totally understand what you are going through. I wrote your post 5 months ago. The info here doesn't seem to make sense at this time, but an important thing to remember is not to go by your instincts right now. Plan A and B are specific ways to get the affair to end, so that you can start rebuilding your marriage.
I had to Plan A for 4 1/2 months! It was the hardest thing I've ever had to do, but the A is ended and we are on the road to recovery.
At first, don't worry about meeting WSs ENs. Just work on the love busters. Don't LB at all. That is the key. It confuses the heck out of them and that's good.
Also, spend this time working on you. Yes, this is definitely the time to decide what you want out of life and your relationship.
Don't push him on the MC right now, but why don't you go to IC? Make sure they agree with the MB principles. I had a hard time cuz IC said "Throw out the jerk." Well, not in so many words.
Now is the time to become an expert at Plan A and Plan B and all the other info on this site. Start doing stuff that makes you happy. Call up some girlfriends.
FYI, FWS didn't tell me he was going NC on d-day. The A kept going, but this is definitely the time that he will be making his decision. The point of Plan A is to make WS realize how much he would be losing if he went with the OW. He may not seem to notice or react, but he will definitely be paying attention to what you are doing. After the A, WS thanked me for sticking it out.
And contrary to what your heart is saying, he has not made his decision. Stay strong and keep posting.
