When you get married you say the vows. They should mean something. Let us start and see what we all said those of us that are married.
"I, (Bride/Groom), take you (Groom/Bride), to be my (wife/husband), to have and to hold from this day forward, for better or for worse, for richer, for poorer, in sickness and in health, to love and to cherish; from this day forward until death do us part."
These are the standard wedding vows. What has changed since the wedding day that causes a divorce?
I think one should talk things through and communicate. Partners that communicate will stay together. It is hard to say why marriages end in divorce. Nothing is easy and they need constant working. If you want something to work you will.
I think it is just too easy today and can be done very cheaply and quickly. People give up and aren't prepared to fight for what they once had and turn their backs on marriage.
