What does the sentence "Love is the grave of marriage" mean?

Because the reality and triviality of marriage bind the illusion and unruly love. But marriage is far more real and stable than pure spiritual love. So there is a saying to the effect that although marriage is the grave of love, I would rather have two people buried in the grave than have a bad ending. In fact, to be realistic, when love develops to a certain stage, two people will inevitably live together, such as cohabitation. But in contrast, marriage is protected by law, so in the case of emotional breakdown, the property of both parties can be protected and divided according to law. In order to avoid worse and more chilling situations. Therefore, marriage is better than cohabitation. Marriage based on love, coupled with careful management, will become your most attached harbor. Therefore, marriage is not so terrible.
