what kind of help are you asking for? If to punish your husband or the other woman - just leave it alone. In my experience, they will end up deserving each other. Neither your husband or the woman involved are worth your time or aggravation.

So far as I am aware, no official body here will award you damages in any way shape or form, they will punish only the "bad guys" which benefits you how?

Walk away. Take the high road. Go on with your life now - don't wait, too much has been stolen from you that cannot be recovered. Don't let this take anything more away from you.
