The problem with that theory is a lot of people who abuse their spouse act perfectly normal until after marriage. Sometimes they can have been dating over 5 years witout an incident, get married, and the person only startd drinking or just become abusive afterwards.
In California, we have a Disullusionment of Marriage, which is like divorce but does not involve any lawyers and does not need a reason for the process, the people just don't want to be married anymore.
