I highly recommend that you should NOT MOVE OUT. harder to bust a D if you are separated.
I also recommend not sleeping on the couch. She wants, out, let her move out of the bedroom. Do not be a puppy dog and roll over (unless this is a 180 for you). Move back into the master bedroom. There my be a risk here in her claiming physical abuse. If you have concerns, weigh the risk/rewards and make a good decision.
