I think that this OM was less preditor than you make him out to be
sure
he started dating your wife...but she said your marriage was over
I am not saying these things to get you bent out of shape at your wife...I DO believe she is sorry for what she did and does want to make amends
I think that the OM is an ass but also was pretty betrayed by your wife and it [censored] pretty badly for him that his livlihood needs to be stripped away as well
it is too bad they both couldn't just be adult enough to work together or...if not, she should have left the company (in my opinion) and not put her boss in that situation.
if she can't handle working with him or you can't handle her working with him then it is time for her to leave
and
as someone who works with restraining orders etc....he is not at the restraining order point (just a heads up)
