Well, my parents didn't divorce, though we kids actually encouraged them to as they were so miserable together
How does the divorce law work in your country?
In the US I believe that all the states have no-fault divorce laws, or pretty close to that.  What it boils down to is that either party can initiate or insist on a divorce no matter what the cause of the breach.
In my country - Sweden, divorce law concerns the disslolution of child support, slimony, custody and the division of property
