And if the suspicions are unfounded?
Then I’d say paybacks are hell. If you’re gonna spy on your spouse you better be pretty certain before you make the move because the blowback will probably end the marriage. Not something to be done lightly, but only as a necessity when all the obvious signs are there.
I would imagine it would be best to stay mum and be happy. What some, who are against trying to find out, think is that it just an invasion of personal privacy. In the world today, with so many diseases and other potential ramifications of a cheating spouse/mate, I am of the mind it can be looked at as an act of self defense.
