Just a suggestion, but why not journal/write about these concerns that you have. Maybe do it up in the form of a letter to H.
NOT one you will necessarily give to him, but one which outlines ALL of the fears/issues you can think of.
Putting them "out there" in writing will help in and of itself. Posting it here will give US a chance to help you formulate any action plans based on them.
Perhaps another thought is to sit down with your H and just ask HIM what this reconciliation means in his eyes.
How does HE see things going? This might give him a chance to allay some of your fears without you having to bring them up.
He might say something like "well we'll both have to work on things"...
You can ask "what kinds of things do you see yourself doing differently?"
