Couldn't figure out how to post here because of the proxy server I'm using, but... if you keep clicking enough buttons...
I honestly have no idea what a "healing separation" might be...
We all "need our alone time" now and then... and I'll admit that I'm a bit gun shy on this one... but...
You mention things are "good" between the two of you... you also mention your W brought it up, but you are the one that moved out... why? As a favour to your W, or were things really that volatile and you actually moved out for your own sanity and well being...?
Because the LBS has a tendency to sit in the mind frame of, "is the WAS just getting used to living alone, practicing for the final D...?"
But here's the thing... and you know the answer...
There's nothing you can do about anything or anyone, except... ???
Yes, you...
If this is a "healing" separation, then by God man...!!!! HEAL THYSELF!!!
And keep the road paved and smooth, and stop asking the R questions, even in the MC sessions... unless directed by the counselor... become that man that your W would be a fool to leave... and if she does... you'll probably have a few options...
