Why won't my husband leave his ex-wife alone after I have repeatedly asked him to...

[AmyM]

...stop talking to her? My husband and I met while working at the same company 6 years ago. When we met, he had been divorced for a few years. They have a 13 year old son between them. They were high school sweethearts, married for a number of years before divorcing. He says they divorced because she was not happy, they grew apart and she found someone else and left him. Apparantly he never got over her or the pain she caused him when she split with him. We were together 5 years before getting married and have a 2 year old together. The ex-wife and I have had problems in the past, due to her lack of respect for me and my marriage to her ex-husband. She has written him letters in the past and sent texts which were highly innappropriate. In the texts and letters she says things about them getting back together someday, or she thinks about him and things like that. He has lied to me in the past about their communication, and I recently found out he did some work for her in her yard and failed to tell me about it. The only reason I found out was by reading a text she sent him. He has told me in the past that he was ending our relationship because he was reuniting with her. I do not believe that she should be contacting him for anything other than emergencies dealing with their son. She also has a live-in fiancee. I just don't understand why they can't leave each other alone. At this point, I feel like my input concerning their relationship is futile and I am considering leaving the relationship. Is there anything else I can do to try and get through to him that I am uncomfortable with their relationship and communication and that I am going to leave if it does not stop??? Help me, I really want to save my marriage from the clutches of this emotional affair!!!
