Welcome to our community. I believe you will find supporters here. Sunday's are slow, but by tomorrow morning, things will start jumping again. I hope you will stick with us and post often. Also, when you finish reading the links on the Cadet's post (we call it the homework), start reading other threads and see how they deal with their problems.
You said your W suffered abuse when she was a child. What type of abuse, and who abused her? Did she ever receive therapy?
You also mentioned some resentment she had about raising your son. Can you expound a little about it?
Do the two of you have children together? Did she have children from her first M? Is anyone living in the house with you now?
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!
