Crazy vs CRAZY!

OMG! Why is it the longer a woman is married the crazier she gets? And its not the good kind of crazy. Married 20 years and she is bat ** crazy now and ** has stopped.
But on the other hand. In the past 20 years I have had a couple of girls on the side. One of them was COMPLETELY diagnosed, on meds, verified crazy. But they wanted to have ** every chance we got. **, ** and more FREAKY **.
So, my question is, WHAT IS THE DIFFERENCE?
Married woman = Crazy with no **
** the side = Crazy and constant ** **
