Know you directed your questions at the guys here, but...
IMO, having the temptation in no way means one needs to evaluate their relationship. That may be the case for some, but the one doesn't facilitate need for the other. To me, it's more of a need to evaluate yourself.. to learn how to keep your thoughts in check, which IS possible. It just takes discipline.
Recognizing that another person is attractive is normal, but that's where it needs to end. *Usually* someone would only approach another in "that way" if they sense some sort of green light. It starts with simple things like eye contact.. especially when it comes to someone you KNOW you find attractive. It can't always be avoided, but use a ONE second rule.. after that, LOOK AWAY! And do your best to not look in that direction again. We say a lot with our eyes.. keep it from ever starting there. May sound stupid, but when it comes to practical ways to deal with "animal instincts", reciting consequences isn't always the most helpful solution. You may need to come off as a cold asshole to some, but so be it! You don't need everyone to like you. However, you do need to like yourself. Laying down your self control & letting random bitches rule your mind isn't how to get it. There's pleasure to be had in knowing you're above it. Focus on that!
And if someone WERE to approach you, be short & quickly drop a line about your wife if the person needs further shutdown.
For the "if you really loved your spouse" view.. what's love anyway? It goes beyond some "feeling". It's about commitment- and that comes down to choice. Choose to be faithful & true to your spouse. We're ALL human & have different inclinations.. but it's definitely not an excuse for poor choices. It's a reason to recognize the bad shit you're prone to & taking whatever steps necessary to not go down that path. It's a reason to ask yourself "what kind of person do I want to be". We are in control of that [emoji1320]
