Wow; with only a few sentences you describe the situation, but the more I think about it, the more I realize it truly shows the difference of perspective.My wife was giving herself to another man, a hung single colleague of hers, for years before I found out. Now I give her to him willingly and enthusiastically. He has no idea I found out, still thinks she's cheating.
What a shock it will be to his smug attitude when, or even if... he ever finds out that you knew all along. Perhaps it was distressing to you at first, and my sympathies to you if that was the case, but to hear your words now; how you have come to embrace it, and taken what many, many men have unfortunately endured and turned the act into a thrill for you.
It is a complete role reversal. Perhaps the other man thinks he's using the husband when in reality it is the unsuspecting man that is being truly used. Not every husband can see with such clarity, or roll with such a punch, but man; good for you on such a unique perspective. You not only took the moral high ground, you dominate the whole damn mountaintop!
You have my respect!
