Yeah, I'm aggressively non-hierarchical in my relationships. I feel like hierarchy breeds resentment, so I don't have relationships beyond acquaintanceships with people in hierarchical relationships, so anchors don't generally work well in that. Not that it's not possible in some senses, but it's unlikely to manifest in a healthy way IMHO.
Makes it really difficult to find others who have similar views. Plus being AuDHD creates issues with my socializing style.
But it results in more emotionally driven support when you don't have to prioritize one person when another is in desperate need of something I could otherwise easily offer if I hadn't spent all of my spoons on an explicit primary or anchor partner. But that's just what works best for me.
