Cheating first if one party or both are loyal monogamists. The problem with some men who cheat is their selfishness. Some won't open their marriage or allow their wife to have affairs outside. Those are the men hate. If you think you want to have your fill, fine. Do it, but don't get offended when your partner does the same.

The shame women go through when they cheat is the reason most women don't but will protect and support their husbands who do. I say it all the time, the best way to cope with cheating suppose is to cheat back.

Don't care about his damn ego. If he disrespected you, then he doesn't value you or the relationship. You owe him nothing from the point onwards. You can keep an affair or divorce him. But NEVER feel guilty for his betray or die in silence from the heartbreak.
