i’m jealous that my master has another slave. - rant

i posted not too long ago about how my affectionate feelings may have damaged my relationship with my master. i also mentioned that i initially felt no jealousy toward the other slave he had been hiding from me. but now, my feelings have shifted—I’m absolutely furious that he has another slave. i don’t understand why he feels the need for someone else. am i not enough? am i missing something? i know his decisions aren’t mine to control, but still, i really wish he didn’t have other slaves when he already has me. maybe i’m just being too needy.
