Why would you want to do that? You have to ask what your motivation is when you have these kinds of ideas. I think that you always need to try to be the better person. You dont need to try to drag anyone through the mud, and your W might figure out what your doing and become royally inflammed, I think that I would at least.
I find that the very best thing that could happen, usually does, he will be in a restaraunt some day when you and your wife are there, totally focused on each other and he will see how happy you are, some happy accident will punish him in just the way he deserves. That judgement and sentencing is not for you to mete out. Like I said in your other thread, put this energy into positive things. You said you have kids right? Older ones, who have a chance to see their father behave in a graceful, dignified way.
IMHO, I dont think that its ever a good idea to carry out actions when your intentions are to hurt somebody, no matter whats going on.
I guess I gave the wrong finger to the wrong man...
