Ok, here are my thoughts:
First, the "other" woman in my first marriage. At first, I hated her, thought she was the lowest of life forms, how could she break up my marriage, blah blah blah. I wanted a piece of her. After looking at the big picture....it was the best thing that ever happened. Unfortunately, I probably should have never married him in the first place. It was a severe case of "I shouldn't have seen the signs a long time ago". And now I am really so much better for it, because I have the love of a truly amazing and wonderful man.
It was very sad for the kids, but we have all gotten through it with minimal scars...and they are both doing great. Good grades and all!!
Second, as for my friend who found herself the "other" woman. I was really more disappointed in HIM. I really felt that he should have finished his business with his first wife before diving head first into a new relationship. They are still together after five years....still not married....but they live together, and are doing good.
I really thought we would get some "other" woman bashing going here.

Guess I was wrong.
I guess we all realize it "takes two to tango".
