What are things i can do to give her space when living together?

If this were me, I would be so angry that I'd be giving her a LOT more space. For one thing, I would not be sleeping with her - I'd be sleeping on the couch. For another, I would not hug her nor let her touch me in any way. In other words, you need to be giving her MORE space - how can she miss you if you won't go away (figuratively)?
