Heartbroken,
Anxiety often leads people to go into a "control" response. As in, "If I do X (or make others do X), the outcome will be controlled and my anxiety will go down."
Sometimes there is consciousness around this pattern; sometimes it's subconsciously driven.
I know that I battle this myself at times.
The problems with the anxiety/control loop are several:
-It sets up a false sense of security. Outcomes often can't be "controlled."
-It interferes with other people's autonomy and enjoyment. The anxious person is so bent on trying to "control" the outcome that they try to "run the show" for everyone--often becoming impatient and angry when others won't cooperate with their vision of what "needs" to happen. Basically, the anxious person is trying to control both the outcome and the actions of others too.
-It fails to address the true underlying issue: anxiety. Because anxiety is the root, this is the real problem the person needs to address. Yet the vast majority of their energy is spent trying to control outcomes, while the anxiety continues. (Basically they try to control the beast instead of vanquishing the beast.)
IMO, you need to give yourself the permission to be in "opt out" mode. Just because your H wants to create his vision of what healing the relationship looks like doesn't mean you have to participate.
As you are well aware, he actually needs to listen to you, really hear you, really empathize. It would be one thing for him to want to take action by offering you possibilties. As in, what if we took a family vacation? Or what if we met my sister and her fiance in a nearby city where we all stay at hotels? However, these should be presented as true options for you--options you can say "no thanks" to and be heard.
A friend of mine experienced the loss of a family member this year. Later on, she supported other people in our circle of friends with their own grief when they also lost family members and what she said really struck me:
"Sometimes you just need to sit with someone in the shit."
Her point was a great reminder that sometimes what isn't needed are platitudes or even action. It's just BEING WITH SOMEONE WHERE THEY ARE RIGHT NOW IN THEIR DIFFICULTY--just sitting in the muck and acknowledging their emotions and validating them.
Often, this is more difficult. We all want to rush to fix. I know I do.
You can try to help your husband understand this...but it seems like you have. So maybe all you can do is have your own back and opt in or opt out of planned activities as you are guided by what serves you. If nothing else, it breaks the dynamic of you participating in your husband's anxiety/control loop fix-it strategies.
Maybe he needs to see that making you a true partner by listening, hearing, and empathizing is at the core of healing--not running around making plans to create the future he would like to see happen.
