[m/f] What will you do in this situation?

To start with, I’m already a horrible person. But it makes me feel more horrible when I think of this one guy whom I can say gave me the best sexperience ever.

We recently communicated again after several years. The guy is now married but he’s still into the game and wants to do it again.

I really want to but he’s married to a woman of a popular church here and is a very active member at that. This makes me feel bad for her to the point that I wanted to let her know about her husband (who also attends the same church she does).

So what will you do in such a situation?
