OIN you say you have a hard time implementing the advice. What exactly do you find difficult about it? (I am not being jerky, I am really just trying to understand)
For me, I knew what I needed to say and do with my H but my H is a master at getting me off track. He can get you talking in circles until you can't even remember what the initial conversation was about. So I get it isn't always easy to remember all this stuff when you are in the heat of the moment.
When people fight change (generally speaking, not you or your W per say) there is a reason for it. So when I say you are afraid of your W I don't mean you are afraid for your safety. I mean you are afraid of doing something that will put the final nail in the coffin so to speak.
Don't fool yourself that your situation is unique. It's not. I know it feels unique because it is your life but it's all pretty run of the mill WAS stuff.
