Hi Marital Crisis and welcome.
I moved your thread from the son/daughter board to the bettering board so you will get more appropriate feedback given your situation. Even if you remain separated or proceed to divorce, you will learn some skills and tools that will help you cope better and improve communication with your wife.
I am at a loss. I am told I need to detach from her and look after myself. It seems no matter what I say, its viewed through her glasses of anger, control and manipulation.
What do you want? Do you want to try to improve things and reconcile or do you want to move on to divorce? It is okay if you do not know. We can support you either way.
Please share more as you feel comfortable. In the meantime, settle in and read. We have a lot of articles tacked to the top of the board here.
Again
