I'm thinking of saying to him that even if he doesn't want to stay married to me, at least it will help us get back our friendship.
The focus isn't on friendships, but it will help you forgive him and the two of you move on together.
My W was talking about backing out on the week of the event, but she did go. Try not to get too anxious. He is expected to cut off the affair, but let him know that no one will know his story, and no one will ask him to prove/confirm that he isn't in an affair.
How about reminding him it is only one weekend as a minimum, and it will help him know he tried something this week.
