No but I was almost that person. I chose differently. I fell in love with a woman not my wife for many reasons.
I'm happy for you, that you were strong enough to overcome your desires and have worked things out in your marriage.
It's rare to find a man who will openly discuss this issue from a man's point of view.
I'm interested to know, how does this happen that you fall in love with someone else? Is it that you are in a situation where you are together a lot - as at work? Does the other woman say or act in much different ways than your wife?
It happens so much in our society & would be a big help to us women, if we knew ahead of time what the answer is, so it does not happen to the people we know & love.
