Soul cob
Soul as a modifier to the word cob refers to someone who completes your innermost self. Cob is a catch-all word that can refer to anything greater or otherwise poorly defined by other nouns. Many things may be a cob, and a cob may be many things. i.e. A soul cob is at one moment a soul mate, soul partner, soul lover.
It wasn't long after we shared our first conversation that I realized, THIS is my soul cob.
