I agree with our posts so far. All I can add is, a real revenge that could satisfy you two ladies would be to just find other endeavors and act as if he never existed. Your lack of grief will puzzle and dig at him enough to serve as a form of revenge you can live with. I've always believed any bad you do comes back to you in time. No need to open an account for later when just being happy will work as well.
