Actually no you don't have to go that far now if things should start backsliding. What you would have to do though is take a step back (calmly) and communicate clearly with him again and let him know...things are slipping back in that direction again (should they do that).
I mean....who would want to go through twice what you two have just been through. I would think that reminding your H that "we're heading that diretion again, lets nip this in the bud now" might be enough....should that happen. Which, I hope it won't.
