I don’t believe @Burrr to be a wuss of any sort, he’ll blindly lick a turd and go back for seconds.Maybe they don't see "doing that to their wife" as you do. Why a wuss.
I believe what he means is, if his ‘bros’ have made vows to a woman forever and they’ll cut their wife’s throat, they’ll surely cut his.
If someone cheats on their wife, why even be married? What’s the point? You make vows to be one in a covenant relationship with that person.
I’m with @Burrr, you cheat on your wife, don’t think your word is gonna hold any weight with me.
I was raised from an early age being told all a man has in this world is his word, make sure it’s strong as oak.
To each their own, I suppose.
