Many who are / have been in bad marriages complain loudly about it. The many in good marriages rarely talk about it ("bragging").

Thus, take such stories online with a grain of salt. Especially since many are blind to their own faults, and therefore can't include them in their stories.

There are many good marriages in which at least one spouse brags about a happy (however that's defined) life of 20+ years and many bad marriages that aren't evident as such until the inevitable "he/she left me and I don't know why" post on Reddit.

I agree that it is important to take a person's examination of his/her self or his/her (ex-)spouse with a grain of salt. And while people are blind to their own faults, you're making the mistake of thinking that divorces are based on falsifiable and rational assessments. Some are. Some aren't. But one isn't likely know the true reason a long time after the fact, if at all.

My thoughts exactly. When the comment you responded to mentioned the word "reddit," this immediately came to mind.
