How Do You Graciously Accept Your Spouse's Faults?

True love is unconditional. None of us are perfect, but our expectations are often unrealistic when it comes to the one we love that we choose as a lifetime mate.  People get divorced for two reasons 1) Failure to correct their faults and 2) Failure to accept the faults of their spouse. Marriage requires forgiveness. What if your spouse is messy and never becomes neat? What if they can't stop smoking? What if they can't lose the weight? What if they keep misplacing things? What if they are always late? What if these faults never get any better - how do you learn to forgive and love them anyway?
