I think you should leave the sleeping on the couch thing alone for now. I totally understand that it bothers you but he is home and before he wasn't. Let this one be for now. When H and I lived in our apt, he use to like to fall asleep watching tv in the living room. It use to drive me insane. Then he realized that it was a power struggle and so he would do it to upset me. I stopped being bothered about him on the couch and it stop being a problem between us. Use a bit of Michele's tactic here, when your H falls asleep on the couch, go tuck him in - give him a blanket. But rest assured that he's home. You have bigger fishes to fry... to me this battle isn't work it. And then think of it like what they say men need their own cave to crawl into and think - let him be. He'll probably come back to the bed sooner if the couch is not even a problem. Act like him sleeping there is normal for him. Say goodnight and turn in. You did it when you were separated, so you can do it with him in the home. IMHO.
