Soul mates become soulless
This continues the idea that Kanye is losing himself due to this exploitation of his former soul mate. After he goes home from this encounter he will be just as soulless as he was before, because he’s throwing out meaning for temporary enjoyment.
Note the clever wordplay here; soul mates without the soul are just mates. This implies a relationship based solely on “mating” (having sex), rather than based on love and emotion.
