Pretty much what Gardener just said. Your boundaries are going to be one of the biggest things. Plus, as long as your husband has any contact with this OW, full repair of your M will be next to impossible. One of the boundaries that you will need will be transparency with your husband. He will need to be able to prove to you that he is not having contact with OW. That means allowing you full access to e-mail, phone, cell phone, phone bills and records, etc.... Shock
