Wishing for liars to live terrible lives does not help your life. At all. It makes it worse.
This comment and mindset is self-destructive. Yes, bad things happen - but nothing is ruined. There is no such thing as ruining, only changing. The relationship changes, the people change, and your understanding changes.
Desperately vying for any sense of sameness, and forcing yourself to continue a life that is not true, doesn't serve you or anyone.
Things can be good. You can get divorced and that can be a better outcome. Things can change.
