I know that feeling. H is always saying how I should not tell people what is going on, and he enjoys going out with me and S because then he has a "family" to show everyone. A lot of people in our city know him and so also know me. I finally said a few months ago no more pretending. If he does not want people to know then he should not be going around with OW; out to eat, football games, grocery shopping, etc. where he knows people we know will be.
I am through pretending that everything is good and if he does not like it then he can fix it. I have changed a lot in the past 5+ months that he has been gone so I am doing my part.
If your wife does not like you saying anything, she can talk to you about it. As long as you are just stating the facts and not putting your opinion in or your assumptions, I think you are ok. It is part of you being realistic about life, and there may be people from your old church who will become great supporters of you and give you some good advice on how to keep your marriage strong.
