A relationship is just that ...
Right or wrong ... legal or not ... did the wife react to something the husband did? Certainly.
In a relationship, after 35 years, its more important for me to understand what triggered the initiating action.
In this case it's easy to focus on the cheating husband. But the wife should do a little intraspection and figure out what made him decide to risk cheating.
Something's missing ...
OUT! OUT WITH YOUR DEMONS OF LOGIC! The woman is always an angel.
Not.
