Great move and one I'm sure your BH will find really helpful especially because you used you're own initiative to do it without being directly asked to.
I've also deleted a twitter ac and I know BH feels good about that as it's a trigger for him. This was about a year and a half ago and I mentioned how i'd like to set up another one recently. As we know, my H is not one to directly communicate his needs and rather than saying "I'd rather you didn't do that" he said "oh, do you really need one?".
I haven't set one up and don't intend to. I'm learning how to read him and it sounds like the same is happening for you.
I'm learning that BS's all have their own way of handling the aftermath of the destruction we cause. Some want to have access to everything, some don't. Making sure it's accessible to them, I think, is a great idea.
Has he asked for a timeline? Have you done one?
