No, I know, and I understand.
But it's just that nowadays cheating became a regular part of someones life, it's just a thing whether she'll (or him...) discover or not. Hell, I'm not even saying that's normal.
It's still hilarious and scary to see so many girls be perfect chameleons. They'll just act perfect, show the things you want to see, only to change their behavior when it fits later on when it's too late
