Thank you for your comments. I realize that there is no delicate way of avoiding my S8's pain. I am trying to keep it to a minimum though.
I am at a point where my W and I are arguing more and more. I have tried to avoid letting here get me into those types of talks but I find that I am losing the will to fight for this M anymore. I can not get her to try and work together so we can just physically separate. All she knows is what she wants and that is all she cares about. This R is toxic... She is toxic... I need to figure out how to proceed as cheaply as possible. Trying not to get lawyers involved but it appears we are going to have to go that route even though we can not afford it. Looking for advice or thoughts on how to proceed. I still love my W but I need to love myself more and save myself.
