Ohhhh Ralphie. . . Another way to look at it is - it took 42 years before the true relationship between your DW and any peaches came out in the open. Allllllll those other years - were you ever missing a peach - that you know of? That's the thing about marriage - it is a true sacrifice. IF she eats two more peaches in the next 42 years I would definitely say you have grounds for getting rid of the thieving wife. Trust is a choice. You can assume that being found out is enough to straighten her out and this episode is done forever. Choose to trust her. THEN watch your back!
