I guess this is a matter of terminology and people definition of words. I consider cheating on your wife to be despicable, amongst other words not appropriate for this site. I've been married for 8 years and have 2 children. Cheating throws that all away. If you are unhappy, get a divorce like a civilized person would do. Don't get with a random 19 year old girl just to do it. And in bringing up public figures from century's ago, I would guess that doing this type of thing was very common and more acceptable back then. I would think we would have evolved as a society more at this point, but many times I wonder. What we need to stop doing is comparing horrible acts to similar horrible acts as if to justify by saying "see, look who else did this, or this happens all the time." Please don't tell me that adultery is ok because FDR did it.
