"The truth shall make you free," but nobody said it wouldn't be painful. At a time like this, you probably do very well just to get through the day without breaking down. It is better that you know, painful as it is.
It's good that you're talking to your priest. I hope he is able to offer you some solace.
Why do women/people have affairs? I understand that there are many different "reasons." Younger people usually do it to make the other partner jealous; as people get older, there are other reasons. Regardless of the reason, it hurts just as much to find out.
The others are right. You need to cut and run. At this point, she is not likely to change her behavior patterns. So sorry.
Scooter, there is a difference between a single unfortunate indiscretion than a longstanding history of repeated wrongdoing. I admire your courage and honesty in saying what you did. If Yeru's wife changed her ways, it would be great; but she doesn't seem likely to do so.
