Seems odd- and yes, a sad commentary on the state of men - guys who presumably are "living the dream" and yet are miserable and so seek this "easy" release - and they lie to themselves, saying "hey, my family is better off b/c I'm happy and not uprooting everyone . . . "
We should normalize and work toward honest, open communication - the demand for this type of "work" seems to indicate something lacking in our model of how work/life/family should be -
Two single, consenting adults in a "sugar relationship" - whatever, it's all good for both - but when one party is married, there's a whole other set of issues.
