FWIW, my H and I had to separate in order to really miss each other. Don't think that moving away, or out is the end all. It isn't.
Matter of fact, this time round, I'm the one pushing for the separation. NOTHING like a big heaping dose of reality to make the WAS grow their brain back. She's in fantasy mode... life would be great... only if, blah blah.
Get that Not Just Friends book. It explains alot, and you can use the psychology to apply in your sitch if she does get a job elsewhere. The closeness starts happening in Email, texting etc and are wonderful ways to get some space and breathing room whilst building rapport again.
BTW, what brought my H back was "going dark". He was only allowed to phone, and it was I who stressed no relationship talks etc. Funny how when you set those ground rules... when they're ready, they'll plow right through them. Stand tough, say things like baby steps etc. Separation, applying darkness and pulling back isn't something to be afraid of, - and yes, it was the hardest thing I ever did up til that point.
