Here's my thing: HIS recovery is HIS responsibility. For you to force yourself to do something that YOU don't feel is helpful to YOU -- that's just you continuing to be codependent and allowing him to abuse you.
That's my stance on this, as a fellow codie. You've spent X years doing things FOR HIM and giving up yourself in order to help him. Doing something that you're actively resisting emotionally, for him -- that doesn't sound like a healthy thing to me. Of course his counselors and therapists and sponsors, etc., are going to have HIS recovery at the forefront of their minds.
Doesn't mean you have to.
But take that for what it is. I'm an unfeeling coldhearted wench (my ex says).
