One you understand that the whole institution of marriage was invented to benefit men at the expense of women, it becomes easier to see through the pro-marriage propaganda. Basically marriage was designed to entitle every man to own the domestic, sexual and reproductive services of at least one women.
Though plenty of contemporary marriages are happy partnerships of equals, blah blah, ery nice if that's what you want, surveys still show that the order of happiness goes: Happiest, married men, next happiest, single women, next happiest, single men, unhappiest married women.
THe endless, relentless propaganda to the effect that all women long for, need and dream of marriage is designed to stop women refusing to be owned by a man on the grounds that they'd prefer to determine their own lives. To an extent, the current emphasis on pursuing, maintaining and 'working at' heteromonogamous relationships is a way of wasting women's time (and keeping them too preoccupied to start a revolution or anything).
