It's sad when a divorce occurs, but worse when one of the spouses cheating comes into play.
At least you finally found out...I still don't know if my ex was sleeping around with another man, or another woman for that matter!!
I've only been on one side of the fence, but it was the "Guy's Side", so I can relate.
The ex wasn't playing the "caretaker" for me, she did the opposite, in fact-and took my money, too!! She kinda threw me under the rug, so to say when she found out I was sterile in the first year of our marriage...took me 10 years to realize that reality! (And many mooore<img src="i/expressions/musicnote.gif" border="0"> )
Anyway, there will be many things that will linger in your head, which will definitely boil your blood. I recommend in the first few months, to find someplace, like a diary, to write all that stuff down...sort of like "Purging" your brain of all that. Writing here can also bring support to your situation.
However, I've found that sometimes even years after the divorce, some questions or feelings come up. I took the suggestion to call it a "Brain Fart", and "do away" with that self-destructive thinking by erasing it from my train of thought.
As for the ($$) dude, he'll probably be tossed away cause she probably doesn't like his body odor or something!
MY BEST TO you through this difficult time...if you've already mourned through the divorce (I had my mourning at least a year before my divorce was finialized), then there are a few more stages to go before you see the clouds parting and the sun ray hitting you on the face.
