Hi hopeful,
Keep posting here for as much help as you can get until you are ready to share with him.
At some point you will have enough faith in your recovery, you probably will tell him. It is a gift to your partner to be honest with him, weird as that may sound now. Think of how betrayed you would feel if you found out after the fact that he was struggling with something you could have helped him with, but he didn't trust you enough to believe you would stand by him through it.
You aren't alone in your thinking, you just may not be right.
Good luck. You can do this recovery thing.
