@Mame,
I didn't say affair, Mame. I noted that it was exceedingly difficult to cover all the possible bases, to touch on every conceivable situation.
And I was speaking for myself for I too agree that taking a second when you've got number one is dumb dumb dumb.
I guess that a lot of times when it happens, someone doesn't think they have number one.
My central point is, people can make mistakes and if a person knows, feels, is sure that they have number one, certain indiscretions can be forgiven. You know, for better or for worse, 'til death do us part.
Remember that song, I forget the title,
"There's been another man that I've needed and I've loved, but that doesn't mean I love you less ..."
I have always been moved by the degree of honesty expressed by that woman and though you might well say that there was a breach of honesty, I agree, there was.
For some, I don't think love means so much as just having someone. To me having someone isn't the test, never has been. Loving someone is the all, the only, the everything, the only thing. That doesn't ever go away and in the grand scheme of a lifetime, what's one or even a few diddles?
I find it perfectly reasonable to accept a heartfelt apology. I don't find it at all reasonable for a person to get hung up on one mistake. I think we've been conditioned to think of it as the ultimate deal breaker.
Silly to my mind, when you love someone, truly, deeply, passionately, without reserve, ... .
