I get the part about the sharing a bed. Living together when separated is also what I've been doing. W has been on the couch just 2 nights and it's so empty for me.
However if she truly feels she is separated and not in a R with you, she won't feel it's disrespectful. My W has truly detached in many ways - and no way does she care about that sort of thing anymore.
