Despised Last Words

We're divorcing for the kids, it would be better for them to not see mom and dad fighting all the time. 

Dictionary.com defines rationalization as to ascribe (one's acts, opinions, etc.) to causes that superficially seem reasonable and valid but that actually are unrelated to the true, possibly unconscious and often less creditable or agreeable causes. Let me give you a more simplistic definition: baloney. 

If you ascribe to this school of thought I suggest you pick up the book 'Between Two Worlds' by Elizabeth Marquardt. Marquardt's research overwhelming shows it is better for the kids if mom and dad stay together. If you truly have the kids best interest in mind, why not try something really radical and stop fighting. You can accomplish this by learning how to work through your differences. It's not hard but it will require you to swallow some of your ego.
