Are people marrying for sex and lust, rather than love?

No, lust, sex and marriage is the normal rhythm of life. Lust doesn't last long but love endures. People in love want to be together married or not. In my opinion, divorce happens when immature people marry foe all the wrong reasons and when their expectations are not met they want out. Getting a divorce is very easy and making marriage work takes a lot of work and a 50/50 commitment.
