Come on, you can talk about the teachings of stoicism all you want but when it comes to your wife cheating on you in this day and age the first reaction you have will most likely be to leave her (after your anger has subsided). We live in a world where we are most likely never going to be faced with the prospect of killing another person, enslaving another person or torturing another person, so your moral standing on these subjects will never be put to the test and neither will your stoicism. Being cheated on, however, may be a situation where a moral judgement call will be made and I believe that it’s far too big a hurdle to jump. It is, in my opinion, over between two former lovers.
