I hope you don't get discouraged posting here. There are alot of reasons why your H could be going through what he is. The trust has been broken and yes, even though it has been a long time, he is still dealing with it.
Sometimes it does take years and it's going to require alot of love, patience and compassion on your part. How transparent have you been since that time? He really hasn't had the time to process anything since he's held it all in.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
