Why it's happening

Sometimes parents split up when they have been fighting and unhappy for a long time.  And sometimes it seems to happen suddenly, when nothing appeared to be wrong, and it's really hard to understand why they have to split up at all.

There are many reasons why parents decide to split up—as many reasons as there are couples.  And with each couple, there might be one main reason, or a whole pile of reasons.

In any case, everyone has their own reasons.  And whatever the reasons, it's never an easy decision, parents usually try very hard to solve their problems before they take action.
