I suppose the big question here blue, is WHAT DO YOU WANT?
I am struggling with that question. I can't say that I WANT rec. I will be posting about that on my thread.
If you WANT controlled separation and you are telling her that's what you want, like a boundary or ultimatum, you should be following through with it. Not using it as an attempt to get her to change her mind.
Otherwise, it is NOT what you want, you should be letting your W know you've changed your mind about it and then carry on. Let her take the lead towards D on her time.
The question about whether she will go for an A if you do not give her the sep is the same as asking if LRT or dark will open the door for an A.
Nothing opens the door for an A. If your W chooses to A, it will have nothing to do with sep or LRT / Dark. She will justify it, no matter your current M sitch.
Only YOU know when you've had enough and are ready to move on.
Are you still attached, are you just loosing patience, are you done, or are you looking for some magic bullet to have her change her mind?
