Although the definitions of marriage and love are relatively simple, everyone's understanding of marriage and love is actually different. Some people get married without love, such as the ancient doll marriage; Some people have love without marriage, because they think that as long as there is "instant" love, it is love; Some people, even with love and marriage, are actually just two people living, and they think marriage is more like "doing business in partnership" or "two colleagues in one unit" Different people have different definitions of marriage and love, which leads to their different views on marriage and love. It's no big deal.
Personally, I think the sentence "marriage is the grave of love" is wrong, because I think love is not a matter of an instant, but a matter of a lifetime, and there may be love at first sight, but the so-called "love at first sight" is definitely not for ugly women or ugly men. What they call "love" is not love, but passion and pornography.
Love is dull, just like marriage, dull and passionate, and can't be integrated into daily life. After all, everyone has troubles and needs simplicity, so love is dull. It's just that people often disguise themselves in love and hide their true colors in order to get what they need, which makes love full of passion, but marriage is extremely dull. In fact, true love, like ordinary marriage, is dull, but it is artificially disguised as passion.
