Does a soul mate really exist?

mammals are built to catagorize information and detect patterns in order to predict their future and survive. as a result, there's an innate predilection to believing the world is ordered, that it makes sense and, as challenges are survived and overcome, that maybe the random events in their lives are even benevolent and parental. the world is fundamentally chaotic and indifferent, however. there are emergent patterns and cause and effect, but there isn't an ultimate fate or grand plan.

it's not impossible that you find someone you get along with really well, maybe not even unlikely depending on who you are. but it definitely isn't predestined to happen, and it is extremely unlikely that you find anyone you get along with perfectly. disagreement and compromise are inherent to interacting with other people in a chaotic and disordered world, but the amount required does vary depending on the individual personalities and experience of the people involved.
