Almost gone

I asked him to move out yesterday. I can't stand to be in bed with him...feels like a vast distance has opened up for me. He says he has no where to go in the same town and we cannot afford 2 rents so I made him sleep on the couch. I am terrified this is the end but I cannot come to grips with how he cries, begs and says he will change if things get really bad with us, like now, then does nothing. If I broach the subject, I get angry before I even start because I am the only one that ever starts and I guess that would be real erotic. If I say nothing, I get angry. If my body was behaving(I have CFS), I would leave myself...I think and hope if I actually leave, it may jolt his brain into action. Has anyone had success with a separation?
