After having read your explication on your situation, I take back my previous advice.
If your divorce is not yet finalized, don't even LOOK at another woman. Don't give your wife the slightest bit of an excuse to take you to court. It's sad and lonely, but at least you have your son. I don't even have that...(plus most people think that I'm still married, so dating has been difficult here, too.)
As far as I am concerned, your wife is your mortal enemy at this point. Since you know that you will get divorced anyway, she has nothing to lose but a lot to gain by taking you to court. If you have proof that she ever cheated on you, you might want to keep that as leverage over her until it's finalized. If it looks like she might try to take you to court, beat her to the punch. If you can get her to be at fault for your divorce, it beats the hell out of the opposite case.
Just for members who don't know my backstory, I recently got divorced after a short marriage, and one of my brothers also has gotten divorced about a year ago. Divorces are nasty business.
