Here's a thought ... See an attorney and file for divorce ASAP. Once you have the ball rolling on that front, continue to monitor the emails. I'm sure your stbx will be really opening up to her lover - if nothing else for emotional help. As it nears time for the divorce, call the lover and tell him you know all about his escapades with his wife - all the way from the beginning. Now, don't blackmail the sucker, but give him enough rope to hang himself (i.e., make him realize what his future with your stbx will REALLY be like - even throw in some dispicable lies about her hygiene, how her beauty is already showing signs of deterioration, how much of a nag she is, etc). In all likelihood, he'll probably ditch your stbx that very minute. So now your stbx will have nothing (ok, by today's laws she'll definitely get something, but not what she wants). ;-P
