I think saying you wouldn't stay is a lot easier said than done. I've seen so many people say the same thing and yet time after time again they get cheated on and they just stay with them.

For me if I know the person I was with had sex with another person it's over.

No **** them

No.

I'm open to the idea of an open relationship, so cheating would mean my spouse was specifically going out of their way to hurt me. No time for it.
