Have you considered going to a Retrouvaille weekend with her? I understand that you don't trust the woman she has been and perhaps still is. But people can and do change if the choose to. I know because I have done it myself, and so has my husband. And we did it with the help of the Retrouvaille program. It is a matter of looking introspectively and deciding what you want for your life, and then living by the choices that you have made.
