Completely agree, with this! No need to announce anything, to step back. Sometimes, detaching, is more a state of mind, than an action.

I am not sure, how often you have contact with them, nor need to have contact with them. I used to come away from near weekly in-law functions with a raging headache. And I needed to learn how to separate myself, and see clearly through to what I found distressing, all the while, still feeling obligated to attend these functions to save face. My health is more important than the drama they bring forth.

(some of)Their two-sidedness was unbelievable to see through, yet, as I navigated the waters, I learned that I wasn't the only one who could remain, present but detached.
