A critical tool for a successful marriage is the ability to forgive your spouse. Being able to let go of past hurts, disappointments and petty arguments is a way to keep yourself healthy both physically and emotionally. When partners practice forgiveness, fully aware that both individuals are capable of hurting and making mistakes, their marital bond becomes stronger. Nursing perceived hurts can hamper the union, wear partners down and make way for hate and extreme bitterness. Practice forgiveness and make it an intimate part of your married life.
