I’m guessing you don’t have a problem with your partner sleeping around either? Though I think a lot more people are coming to that way of thinking, more the return to the turn a blind eye culture i.e. treating it like it’s not a big deal.

In a way, it makes sense, as sex is more for pleasure now rather than baby-making like it used to be, there is more reason to turn a blind eye now than there ever was in the past. So long as both parties are happy with each other at home. Sort of a let people experience life, while being there for each other at home.

It will be interesting to see what relationships of the future look like! Considering how much infidelity there is, it is likely that it will be a more open type environment. But who knows.
