Hi K067, I'm not Sandi or Puppy, but till they come on here, could I offer some words of encouragement?
I think it's great your H is trying, and it appears trying hard. At some point in your sitch, what would you have given for that? Hold onto to that huge positive.
You're in pain, and better posters than I will tell you about detaching. There will be triggers that will set you off, and they may not go away any time soon. It's your choice what to make of that. We all have different thresholds for tolerance and reconciling with difficulties. I would suggest you consider getting individual help with your struggles if it continues eating you alive. Those images may never cease, but you have to look to a future where they don't tear you apart even if you do not like them.
Time. Time will help, so give time time. I can fully understand the pain and thought processes you describe. You have to eventually decide you do WANT to get past this and work out your M. You can, but you have to empower yourself to let go of many things.
Be strong!
