Please, a prayer to save my marriage

Dear Lord, and my dear Patron Saint Martha, please hear me and help me save my marriage. I have time and time again made mistakes and this time my husband has resigned himself towards me and our marriage. I do not want a divorce. I love my husband and our family. We have two small children ages two and four....I cannot accept divorce. Please help me and please allow me another chance to redeem myself. I am so scared, so frightened and feel utterly alone.
