Actually OM typically have done worse. The OM my W is onbsessed with is a multiples time serial cheater. Even left his family once to be with the OW. Then came crawling back to his W after kicking the woman to the curb after ahe left her own H. OM since theb continues to mess with other W. They leave their families, while he stays with their W. Then repeat to another W, until he eventually met mine. OM E told me all about her H behavior. I told this to my W, but she is going to learn the hard way as usual.
When it's all said and done. My W is going to lose me, S13 respect, home and has already lost close/oldest friends due to her behavior. All over some man who will never leave his W and family. I can honestly see my W playing in traffic once this fog lifts. Because she has contemplated suicide in the past for less.
So trust me, OM is far from being better than you. He just happens to be new and exciting at the moment. My W will eventually see that she is nothing more than one of his booty calls once every couple of months.
