a. LK, you need to get some firm boundaries in place to protect your home from this affair happening again. b. LK, you need to inform your wife you need her to open up her email accounts and cell phone records for you to feel safe again c. LK, you need to invite your wife to attend family therapy first.
Until this affair is OVER... And I don't believe her... Yet... You need to be in protection mode and keep a CLOSE eye on her.
Ignore all the excuses about why the affair happened. You can explore that later. Do the necessary work to CONFIRM :
a. The affair IS OVER b. That a rough patch in your marriage WON'T lead to this again
Once that is confirmed, outside of you just asking your wife "is it over" and "please don't do this again", then you can do the repair work.
I don't see much point in even touching Sex Starved Wife or any other text on Sex until you are CONFIDENT BEYOND BELIEF that this affair IS at an end.
What precautions is your wife taking LK to ensure this won't resurface at work again?
Is your wife looking for work elsewhere?
Has the OM's wife been informed?
Is he moving to a new location?
Anything changing at WORK to safeguard this marriage?
