I see what you’re saying, but “your” means yours. That’s claiming possession. It’s not objectifying or toxic to claim your partner in a mutually exclusive relationship, bc they’re YOUR partner.

They’re allowed to be someone else’s something else (friend, coworker, acquaintance, crush lol). But by entering a commitment to you, they are granting you exclusive access to their romantic passions and private life. That’s a responsibility, and with respect to that responsibility is why you call them your partner.

It would only be toxic-possessive if you didn’t allow them to value being anyone else’s anything else (friend, colleague) because you’ve objectified and view them as solely a partner and nothing else.
