Well nothing very subversive. In the first place personally I don't seem to experience jealousy as most people do. I just don't feel that gnawing, suspicion that seems to be all encompassing for many folk. ( I do envy sometimes BTW but that is different)
So I find it really hard to empathise with someone who is or fears they are being cheated on. I make the right noises because I have learned what is expected but I am not feeling their emotion in the way I would if they were experiencing the pain of bereavement, or going through anger or anxiety or joy. Or at least I assume I have an inability to know what jealousy feels like, that explains my difficulty understanding people's reactions to it.
So I find people's reactions to infidelity quite difficult to handle. In the first place fidelity is an entirely man made construct. It isn't innate to our species. Instead I believe the sacred nature of fidelity is peddled by the ruling classes as part of a means of (among other things) controlling the masses and maintaining their own power.
In the second place there seems to me to be something logical about fearing infidelity and experiencing jealousy as the precursor to possibly losing something/someone you love and value. So the reaction of kicking someone out of your life on discovering they have been unfaithful makes no sense at all to me. It takes you from fearing something that might happen if your partner 'cheats,' to making absolutely certain of such a feared outcome.
Finally someone who has a philanderer for a partner often has the constant confirmation of being that persons's first choice. This is assuming its the sort of guy who plays away for a spell and then returns to the spouse until his feet (or something

) itche again. In most cases it will be the other woman (why do we never speak of "the other man"?) who is dropped not the wife. In many ways I think there is something far more committed and affirmatory about a person who plays away and chooses to come back of his/her own free will than one who just picks someone, grits their teeth and tolerates whatever.
ETA - On reflection I can, maybe, empathise with the pain but not the outrage that often goes with it.
