Marriage is definitely not a joke, but it has been rounded up in a mushi act by all "eternal love" books and romantic art. What marriage is planned to be is an economic union and to guarantee the rights of each side in the family. If the husband and wife love each other - great, if not - well there can never be a full happiness. 
Marriage is not a joke but men are making it a joke these days by getting married to a woman and thinking they own her. The marriages that used to be a lifetime commitment earlier does not even make sense these days. Whether love or arranged marriages, it is necessary for both the partners to respect and trust each other rather than be deeply in love. These days people believe in trial and error and then such cases of marital rape and assault are revealed.
There are so many celebrities as well who have been victims of such crime and they come out with it while some hide it just to save the marriage. It's not a sacred relationship that you need to stick to it just for the sake of being in a legal relationship and the man takes advantage of this helplessness.
