Why are people against divorce?

I could never understand why some people are sooo against divorce. Like if he is abusing you, you should leave. If he is abusing you and you have kids, LEAVE. I've seen this in real life and this app way too often. Why are some people so against divorce?

People change. Some get married way too fast or way too young. Times change. What was once a happy couple, doesn't mean it's always going to stay a happy couple.

I agree that couple's therapy is an option and that some problems can be worked on. But sometimes relationship don't last and sometimes relationship's shouldn't last.

Like?! Those of you who are so against divorce why?

I love my husband more than anything and we're super happy and I don't see it changing. But if he became a cheater or abuser, you bet your ass I'm leaving him, especially if we do have kids. I'm seeing it as doing a favor to the kids, setting an example that sometimes people shouldn't just stay in a relationship and stay miserable, that they should never tolerate disrespect, abuse and cheating. That relationships are supposed to be healthy!
