nds, my W has recently commented about how she feels her control over her 'personal space' is coming back. The couch thing may just be your W's way to feel in control of her personal space. Just a thought. I'm not sure I would interpret it as her somehow 'running away' from you - this is based on how the rest of your sitch is.
The question I have is did she used to spend every night on the couch? Or more nights than she is right now...or has the frequency remained the same?
