First of all MC isn't even sure there was a mistress, right? I mean was there a concrete evidence pointing out that he indeed did have a mistress, if so she could have sucked it up for now and keep tabs on the guy who will possibly cheat in the future since yk she regressed.
And who in their right mind announces that their partner will cheat in future.? Like it's okay if he doesn't but doesn't it give them even more of an excuse to paint you out to be a crazy human and be more careful to do the deed?
