Boundaries need to be obvious and the must be enforced.
How would you know if she was being intimate with someone?
Is your hand on the trigger and you WILL file if she is intimate with someone? The dog's gotta bite...
From what I can tell, you two have had a really interesting definition of piecing...
But for the most part, aside from I have probably been at this a few extra months... our experience is pretty much the same.
My W does not feel M, but does not want to D (well, maybe she really does, now) and was pretty happy doing absolutely nothing in one direction or the other.
Now I am not in any way encouraging this. But in my case, I will no longer be M to someone who does not want to be M, does not believe she is M, and acts like she's single. I have been separated for 15 months. I will be filing.
I would recommend a trial separation to start. But really, and I'm going to admit that while I did change to some degree, I could do more, M to me wouldn't be much different now for my W. But... until the D is final, I will keep DBing. Maybe something will click for my W. I don't know.
So I'm just saying... if you can take it slow, do so. And keep DBing... for your future...
