Ye the last few interactions with your W have been negative so i'd say dont contact her, if she contacts you then reply if you need to but otherwise dont answer.
You really need to keep GAL and working on YOU - you need to work on letting go of your W and M because that's truly the only way that you can move forwards from this. If you feel you want to write to your W then do it but DONT SEND IT, that way you get your thoughts out but without sending to her.
Keep your chin up, keep focusing on YOU and not her. You are what is important now & your the only person that can make this situation positive for yourself.
