If you start to like a guy, keep him and teach him his role. Catch him off guard and implement a mandatory one-sided open relationship. You forcibly rewire his brain to accepting that he is less than you and he can finally relax once you reallocate him to a lessened status. He can only experience happiness when he’s taught that he’s worth-less. If you care about him gift him that sense of worthlessness and he’ll worship the ground you walk on. You definitely don’t have to dispose of him if you enjoy his dick and he intermittently behaves in accordance with your standards.
