By this standard, you can know nothing and discuss nothing without a PhD in the subject matter.
I'm very confident saying most people can't divorce their spouse in a heartbeat no matter the reason, it is entirely detached from anything I've ever observed about relationships, marriages and divorces, over everyone I've ever known in my entire life.
Most people I know couldn't even be sure whether they'd be happier outside of marriage, many people I've known have stayed together even though they were both miserable, many people I know have had a divorce, when either or both wanted it and were miserable throughout the proceedings. That's not even going into breakups in non-married couples which follow different dynamics but aren't generally easy either.
