Yea I got you I don't respect cheating regardless myself but to get entangled in some nonsense you may have no control over depending on who the spouse is. Just needlessly put yourself in unknown crosshairs. We've all heard crazy stories.
I've never cheated and I been married for 21 years. I have no reason to suspect she has either and its nothing I've ever sweated we both had childhoods with divorced parents and didn't want that for our kids so behave accordingly.
