Okay, this "I need YOU to leave because I NEED space" thing is ridiculous. This is where being a man and standing up for yourself needs to come back to our society.
If my wife came to me and said she needed space, move out. I would have told her that if she needs space SHE should move out.
You seem to be doing a lot right here, except fixating on her not discussing the R. Just let it lie, These things take a long time to work themselves out. When she is ready to discuss the R she will. You need to be prepared about how to handle that discussion.
