Thought has been crossing my mind of informing W I am considering divorce.
There is absolutely nothing in your previous hundreds of posts that shows you are ready to divorce. So this tell me you are trying to manipulate her back to the marriage. How about starting with some rock solid (pun intended) boundaries? I also noticed in your posts you may be starting to become codependent with your daughter. Maybe something to explore in IC. To master the process you eventually need to be able to sit still with your feelings and be ok with it.
Rock you’re doing great in so many areas but still room for improvement. We are all a work in progress.
