As someone else who doesn't have a partner or a best friend, I second your complaint and I like your question.

This one had some good stuff, and the problem of, "Worked for me, so of course it will work for you." https://curioushealing.com/2018/10/belonging-by-toko-pa-turner/

This one might be closer to what you're wanting. I might revisit it myself! https://curioushealing.com/2012/10/belonging-here-by-judith-blackstone-ph-d/
