I see you standing in a storm, tossed between grief for your husband's wandering and a sorrowful awareness of your own failings. It is a blessed sorrow, this humility that confesses, "Pray that he forgives me for the sins I have done as well." For where there is such a heart, there the divine Physician is already at work. The wound that is hidden and denied festers unto death; the one laid open to the light is already halfway to healing. Hold fast to this: the same Lord who told the woman at the well, "Thou hast had five husbands, and he whom thou now hast is not thy husband," did not speak to condemn her to despair, but to draw her to the living water of His grace. He knows the full measure of your husband's lustful desires and your own offenses, yet He still seeks you both.
Your husband has indeed fallen into a pit whose mouth is wide in this world. Does not the lust of the eyes, inflamed by the stage and every kind of spectacle, tear husbands from their wives and make a mockery of the marriage bed? I have seen how those harlots of the theatre have severed countless husbands from their wives, drawing men captive from the very marriage chamber itself. These are the snares of the enemy, and your husband is caught in them. Yet do not lose hope, for the bond of marriage is not a human invention but a divine law. The woman is bound to her husband so long as he lives, and he to her. This one-flesh union is a great mystery, speaking of Christ and the Church. Will Christ abandon His bride when she stumbles? Neither, then, should you abandon your husband to his sins, nor he you, though the path back requires a turning of the whole soul.
Your task in this holy war is twofold: unceasing prayer and a life that silences accusation. Honor your husband not because his deeds are honorable, but as an act of obedience unto the Lord. Let your chaste and respectful conduct, full of the fear of God, preach a sermon to him without words. Do not be inquisitive about his goings out, nor nag him with accusations, for these things often spring from a burning, fearful love and can, if mishandled, push a man further into darkness. Love him for Christ's sake, despising the money and fleeting pleasures that so easily ensnare us, and look only to the excellence of the soul. Your quiet, steadfast faithfulness will be a stronger reproof to his lust than a thousand sharp words.
But you must not neglect your own soul either. You ask for his forgiveness, and that is right, but first seek the remission that comes from God alone with a full and complete repentance. Do not merely gaze upon your sins, but flee from them with such fervor that you taste the heavenly gift anew. We are not without hope, for there is a repentance that can renew the soul. Though the laver of baptism cannot be repeated, the medicine of a tearful, transforming confession can restore the joy of salvation. Let the blessedness of which David speaks be your portion: "Blessed are they whose iniquities are forgiven, and whose sins are covered." Strive for that blessedness yourself, and become a living icon of God's mercy, so that your husband, seeing you renewed, might be drawn back from the precipice of his own sins and be restored, with you, to a marriage that reflects the chaste and joyful union of Christ and His Church.
