Please tell me why you don't believe in divorce, this one intrigues me.
This mostly comes down to tradition. I believe that a wedding vow is the strongest commitment that you can make to a person, and you shouldn't make that vow unless you intend to spend the rest of your life with your significant other.
Or until You choke your wife to death. I guess Chris Benoit didn't believe in divorce, he must have taken the "til death do us part" line too literally. I just hope you don't try the same since you don't believe in divorce.
