Is a dead-end marriage where both argue frequently and are miserable.. is that just as bad as divorce?

Is a dead-end marriage where both argue frequently (yelling matches and insults), are miserable and they haven't even been intimate for years but live as roommates just as bad as divorce? Then that very same couple posts happy pictures on FB on Valentine's Day, Christmas, etc, about having the happiest moment and even they appear hugging each other but it's all a show. Isn't that just as bad as divorce?

Obviously if it gets to the point of insults, neither boundaries nor respect has been established.
