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.
This supports the “Chief Keef” side of Kanye’s claim that “bitches can’t handle [Kanye]” when he’s drunk. Since getting drunk and acting out has allowed him to get back with his ex and completely dominate her, he has no motivation to be a nicer person.
