Look at some point you going to have to sit down with your wife and tell her you know she seeing the OM when she leaves. This will not stop until you expose to her that you know and then state you will expose to everyone unless she stops.
It looks like you don't have much other than she leaves for long periods and doesn't go where she says she does. She may feel that she is still pulling the wool over your eyes. If she knows you know then she just might stop.
Stop being afraid...it is not helping!! She probably thinks you know something is up and that is why she is using sex to placate after she has been with the OM. Just to keep you quiet.
If I were you, I would stand up....grab my balls!!!....and then confront her. Have a exposure plan. Does OM have a wife or girlfriend?? If so that would be the first place to expose. Then I would expose to her parent/family and then if it still doesn't work then everybody including your family etc.
By your posts this has gone on for awhile...stop it now!!!
