Its really a man song. By "man", not to be offensive to the opposite s**, is to try and take responsibilities for your actions. Like "man up, or shut up", that sort of thing. He was there, he had his chance, but he turned his back because it was the right thing to do. And I think, though he himself made his life miserable as hell, he made the right choice. Yes, life is for the purpose of seeking happiness. But let us not forget that it is not at the expense of others. He has a family, waiting for him, imagine the poor child growing up without a father simply because of another woman. Plus the fact that he's not really sure that this woman was that one great love. At this modern day and age, love has been commonly associated with infatuation. Surely this fellow is simply bored of his marriage, causes which may be attributable to him or his wife. But having a sudden rush of blood caused by a mysterious woman cannot really be said to be love. Reason is, love is something developed after a few round of conversations, laughs, or some get togethers. Its when you know something about the person, other than the physical, that you find something to love about. Bottom-line is, I agree with the guy's decision. He did good. He was man enough to take into account all the necessary considerations before he took the leap of faith. At least, as he faces the sunset, he may have lived miserably, but he lived it with a clear conscience. This is what a real man should be.
