I have been having similar feelings/thoughts/meltdowns. And I am not getting half of what you are getting from your H right now. Imagine if I ever get to that point!!!! (I actually shared with him a few of my triggers that ruined my mood last we went out, still havent heard from him-via email).
For me, it feels that once I get these reassurances (and keep getting them) I will at some point be ready to get rid off the control these images/triggers have on me so that I can register new memories/emotions/feelings.
IMO, it sounds that you are doing great. I think time is your answer... (and drinks/medication/shopping therapy/ etc etc LOLOL) Stay strong, you ARE doing great. K
