If beauty is tightly associated with facial symmetry, then why doesn’t everyone have their hair part down the middle?
It's possible that having certain asymmetrical elements ENHANCE the symmetry of your face.
If everything is symmetrical, then any little imperfection or flaw will stand out like a sore thumb.

Do people get partners because as we get older we have less friends?
Personally, having a partner is not a replacement for friends. There are emotional needs that my partner fulfills that my friends can't and vice versa.
A partner can definitely become a best friend, but i don't think it's healthy to have every role fulfilled by one person as it makes you very dependent on them.
