I like your explanation for this. The way I look at it is, I don’t think we’re built for monogamy. With that in mind, it’s one of the many reasons I prefer being in a poly relationship with the right person.
It takes the idea of cheating off the table. In theory.
There’s still the possibility, of course. Whatever parameters you set can be broken, crossed, etc.
I believe in that situation, the person crossing those boundaries is just determined not to be ethical, to be honest.
There are situations where cheating is the catalyst someone needs in order to move on from a relationship. I’ve known people who just felt they COULD NOT leave their significant other for one reason or another, even though there were many reasons they should. But for some reason, the opportunity to be unfaithful arose, they took it, and it was like a light bulb coming on. They were able to see it was time to leave.
Great piece, Sam! ❤
