P.S., I know b/c this is a DBing forum, many will rush to your side to say they survived an affair, it can be done, you can do it to, you can "let go," etc. That's great - there is a lot of support. IN EITHER DIRECTION.
But ultimately you have to be the one to make the choice about what you know. You have this power, May. And it will teach you to trust yourself for the rest of your days.
Step back into your power and stop being a victim of the unknown. Know what you know. And decide what to do with your life and your marriage.
