Only wrong 97% of the time? Let me guess - you’re in the other 3%?
Not me, but I was. Called up from the reserves deployed to Afghanistan the wife started sleeping around. When I got home I filed for divorce she fought me every step of way extending it out while spending the nights with her BF.
So I had to pay for her sexual excades for years while I obstained, I never cheated on her.
Finally in 2006 the judge divorced us, and then she contested that.
So yes, there are some that had my experience that I would understand if they strayed.
