response: Um for various reasons!  Some examples are a personality clash, both or one of the spouses not having enough independence, and sexual incompatibility.
original_response: Yes, that's a huge reason. Also, lack of sexual compatibility and lack of independence leads to a lot of divorce.
history: Divorce is a tough process to go through. I divorced in 2001 after 15 years of marriage. Oh really?  Did you know it's also called dissolution of marriage?  It dissolves the matrimonial bonds, under a country or state's rule of law. Do you know much about the laws governing divorce? I do!  Monogamy is legally required in most countries.  Thus divorce frees each former partner so they can marry someone else. I kind of knew that.  I know about my own situation, but why do most people get divorces?
knowledge: Reasons for divorce vary, from sexual incompatibility or lack of independence for one or both spouses to a personality clash.
