I know divorce is quite common in America, where it isn't that difficult to dissolve ones marital union. I have been married over 22 years, so I guess it's hard for me to understand why it can be so easy for some people.
Has divorce been around as long as the institution of marriage?
Divorce didn't become available for many years after marriage. Divorce laws vary around the world too. Most countries require a court to resolve many issues like child support, visitation, alimony, etc.
Is divorce prevalent in the United States?
Oh yes, with many reasons that one can divorce, such as infidelity, controlling spouse, financial issues, incompatibility, etc.
