As long as expectations match reality. One statistic from the US that surprised me was that women file for 70 percent of the divorces. In case of college educated people, 90 percent of the divorces are filed by women. 

If I exclude the possibility that 90 percent of the divorced American men were terrible husbands, the only explanation is that women were disappointed with marriage. Because they expected something more/better. Men, on the other hand, seem to be satisfied (or American women make fabulous wives).
