S4H & Lolal, Thank you for your advice. I believe for me the affair would not be a deal breaker. My H has never done anything like this in the 16 years that I've known him, so I don't feel like he is a habitual cheater like some people I know. If he decided to work on our M, I believe we can work through an affair.
My problem is I'm not sure how long I can wait for the affair to fizzle. I guess I will know when I'm done. But I would like to know what I can do now, that will make him start second guessing being with the OW.
