People have responded to your post - you are obviosly not reading any of them. so I will repeat
IF YOUR WIFE STARTS SLEEPING WITH SOME ONE ELSE SHE IS NOT HONERING HER MARRAGE VOW TO YOU.
You seem to think that marriage is some kind of joke, that when it becomes inconvenient the person should just be able to move on and start living with some one else.
If I were in a PVS for more than a decades because the courts wouldn't allow my wife to remove the tube, I'd want her to move on with her life.
