TM, in my sitch, I moved to the living room couch... then the basement couch... then out the door to another building...
When things were still "OK" (maybe late 09 / early 10) and I would go to the couch. I started doing the "that is MY bed, too. I WILL sleep there." And so I would go back to the bed.
Even now, I think to myself "We are not D, we are not legally separated, that is still MY house, too." And I think about moving back in. Not sure how well that would work.
Why did I go back to the bed? To prove a point. But was I proving a point to HER or to ME?
What statement would I be making if I moved back into the house? Would I be doing it to prove some point?
So the questions to ask yourself are:
+ WHY would you move back into the bed? To prove some point?
+ In what way would it HELP the situation?
+ In what ways might it HURT the situation?
+ Do you think it might neither help NOR hurt the situation?
And then what ever you decide, you get to live with the consequences...
OR 
?????
