Marriage is the grave of love. This saying comes from many literary works and popular culture. It is often described as the end of marriage. Love is no longer romantic and passionate, but transformed into kinship. There are many different perspectives and explanations behind this statement. Marriage requires more time and energy to take on more responsibilities and obligations, which makes love tired and difficult. Once a marriage starts, these responsibilities and obligations will become more onerous and make love more difficult. Marriage can ruin romantic and intimate relationships. Marriage requires a lot of interpersonal problems such as communication, jealousy, arguments, and a disharmonious family atmosphere. These will affect romantic and intimate relationships. Many marriages are long-term promises, meaning that both parties need to continue to pay attention and pay attention to each other in the future. However, this kind of commitment may cause the two parties to no longer pay attention to each other as they did when they were in love and gradually transform into a dull lifestyle. Some people think that marriage is a social system rather than true love. Marriage might limit the freedom and choices of both parties, making love less free and diverse. Although this statement might have some truth, it could not be generalised. Everyone had their own experiences in marriage and love. The important thing was that no matter whether the marriage ended or not, everyone should cherish and manage their love to make it deeper and better.
