Hi Keefa, welcome to the community. Your W sounds very familiar, sorry to say. I think more will come to light about her activities with this man she is sending naked pictures to, and I think it's been going on before the bomb dropped.
What are the ages of you and W?
I suggest you read the links that Cadet posted, ASAP. Ask questions as they come to mind. You have a lot of information ahead of you. I hope you can post every day.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
