Not going someplace you really don't want to go is actually pretty healthy. Your body knows what it wants, so we need to pay attention to that resistance. Of course, it tells us it wants alcohol, too, but we're working on retraining that urge.
Good for you for confiding in your husband. His lack of reaction may just mean he needs to absorb it all and doesn't know how to react, though I imagine even a modest show of support would be comforting. Most of my family knows and a few of my closest friends, but I don't know how many get it or even try to understand it.
When I told my then-now-ex BF that I was trying something radically different, he didn't even ask what it was; he had already written me off for yet another relapse (although he had at times been the most co-dependent, enabling partner one could imagine.) He wouldn't even take me to the doctor. Sorry for the sidebar; he's been reaching out to me again and I need to remind myself why he/it's not a good idea.
Let's all have a good week, shall we?
Cheers!
