Hi LH- To a certain extent, I've been in your shoes re. H moving home, but into the guest room. Provided that you still want to save your marriage and live as a family again, proceed slowly. He has taken a big step and the two of you need to gradually rebuild the closeness and trust. If you are continuing to make progress then try to focus on that progress and less on where he is sleeping in the house. You'll drive yourself nuts during this early part of the reconciliation process if you look more at what is missing and less at what is developing.
Some of the most difficult times for me have come when I wanted more and more, faster and faster, and needed to center myself again to see "the glass half full." I'm not saying that all of this necessarily applies to your situation LH, but give yourself a chance to relax and enjoy each phase of your reconciliation. Best of luck with everything--Jamie
