I really love Dr. Psych Mom.

...the problem is, once either side steps out to get that elsewhere, it is no longer a marriage. The promise is broken, the relationship has changed.

Maybe the problem lies in what we say a marriage is.
Is every marriage dissolved by an affair?
I've not heard that.

Is one affair, three nights of passion, the end of a marriage if both spouses fight to keep it?
I see some people who admire such fervor for keeping a relationship.

Is breaking the promise instantly ending the marriage if the break is forgiven?
If multiple breaks are forgiven, does this commenter get to declare the marriage dead, even if the participants don't?

If the forgiveness is given in advance, is the marriage dead?

If extramarital sex is not seen by the participants as objectionable, does this guy get to declare the marriage null and void?
Ah, this last one gets a lot of agreement.
Closed marriages where spouses cheat may still be marriages.
Those that are honest with each other are a sham.

I largely agree that is society's view, but should it be?

Isn't that not just a little fucked up?

I love Dr. Psych Mom but she totally avoids the negotiated infidelity option most (all?) of the time.
Maybe she's judged it would garner too much animosity.

I expect it to be commonplace ten to fifteen years from now.
