no.

it's not like human relationships are static monolithic closures that spring forth fully-formed when two people meet. they're not quantifiable or even easily comparable.

people change over time, their needs and desires change over time, and as they explore themselves and learn from each other and make mistakes or amends they build and damage relationships. preferences will shift with all of these. there is no "best" person who can synchronize perfectly with your changing self, and even if there were, it wouldn't be a healthy relationship, it would be more like slavery.

people who have been as close to me as anyone ever got are now as distant as possible. some folks that i used to think i could never spend much time with are even closer to me now, and our future together seems inevitable. it's not that some weren't "for me" and it's not that any of them are the "best", or even necessarily "better". the ones who are gone now aren't even incompatible with me as i am now. it's just that over time some relationships either connected or became unsustainable.
