Yeah, how about couples saying “our marriage is so strong I don’t mind if the other flirts shamelessly.”
aries2756; strong marriages are built by being faithful,
and really connecting to your spouse, and strong marriages can crumble too. Being irresponsible, or putting oneself into a situation that can lead to inappropriate behavior, or temptation,
Is not a recipe for continuing a strong marriage.
Chazal have rules in certain situations in where being with one’s spouse has the power to protect from certain behavior.
It is clear that without being with ones spouse one can easily fall prey to halachic as well as marital problems.
I’m not saying yes or no, i’m just saying be aware of what it can cause. Giving a free pass to someone who has a strong marriage to do something that may undermine that very close bond, is unsettling.
