Thanks to everyone who responded. For some really good insight in response to my question, special thanks to Holly and Marilyn.
For Clayfish and others with whom I still disagree, I still value your comments, and thanks for offering them. The disagreement is that some think that cd-ing is only a contributing factor in breakups, while I believe that cd-ing is so intolerable for some SO's that breakups happen because of it alone. It's the straw that broke the camel's back theory versus the litmus test theory. We can agree to disagree and still have friendly discourse.
Maybe the question should be left to others. After all, we are not impartial observers. Thanks to all.
