We are in similar situations. What I'm learning is that the focus can NOT be on fixing the marriage. The focus MUST be on your H fixing himself. What concerns me is that I don't see much evidence of that. Especially when you describe him going back to relying on you for things such as packing etc. If that was something he changed when he left, it's likely because in some way, it bothered him. Falling back into similar patterns is SO easy. But as it's stated over and over, we cannot have our old marriage back. It didn't work the first time. It's not going to work again.
Over and over we are told that it is not our fault that the spouse has an MLC. And that's true. So when they come back, it makes NO sense to try and "fix" the marriage. The MLCer needs to fix themselves. The problem is that unless your H realizes this, you can't do this for him. I may be wrong, but this is what concerns me about your sitch.
