No marriage can survive without the foundation of trust.  This simple truth is so fundamental and basic to a healthy marriage that few of us stop to think about it.  Without a profound respect and faith in each others actions and thoughts, a marriage can not progress and grow.  The same is true with a personal relationship.  A committed relationship, a loving marriage where two people learn to love and grow with each other, can never blossom without the fundamental prerequisite of trust between both partners.
