Room Divides and Organization….HELP

Room Divides and Organization….HELP

I am OCD as obvious by my closet.

My girlfriend moved in with me about five months ago and about a month into it I thought I might have to kick her out, but have since been working on organization for the unable to think about organization. AKA= HER. Because I want to marry her one day and our clash in cleanliness is the biggest/only real problem. So I made an area just for her, that she can be a slob in. I need a creative way to divide it, right now we just have bookshelves making a wall and those will stay, but I don’t want to be able to see her area at all unless I walk back there. So any ideas??? This is the room that needs the divide behind the bookshelves, I’d also like to know if anyone has any better ideas for the bunny cages, one’s on top of a desk and ones below, they can’t go together in a hutch or I would have done that. So much easier when it was just mine! Here is our couch when I got it and now..

This is part of the bathroom where I made a small curtain to hide the cat box! I need some suggestions for where to put everyday things that you use in the bathroom, we have a really small medicine cabinet that you can only fit a toothbrush and toohpaste in
