why the divoce rate is so high?

people nowadays at my era.. take marriage too lightly. They don't consider that this is one of the sacraments that God made Holy for the people to undergo and yet they still do it. They get married at a young age then get divorced. Or they know each other a month or two or even shorter than that then they get married. That's what happened to my tita but they're still together because they are still freshly married. i don't know when they'll separate, not that i do want them to separate but i just don't trust the man that he married. He even showed some attitude against my tita's loved child so i concluded how pitiful the child is.
