Have you and your H ever gone to a MC after everything happened?
What you're going through is called a "trigger". It's similar to post traumatic stress disorder that soldiers go through. Certain things will set you off and send your emotions out of wack. It could be a date, a song, a restaurant, etc.
Your H needs to continually make you feel safe. If you still aren't feeling it, then I would suggest you both go to MC so that the both of you learn what it takes to make each other feel safe and trusting.

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