I woke up this afternoon feeling so strange. It’s not my room, it’s not my bed, and nothing feels familiar. My family isn’t here, and suddenly there’s a man, my husband, sharing my personal space for the first time. I don’t even know how to explain it, but I feel like an impostor just walking around and doing things in this place.
I think there is a misunderstanding here, the problem people have with your comment is not the meaning of it, but the words you chose.
Calling someone an abused wife is effectively pointing things out (as in direct description), but calling someone a pet is not pointing things out, it is making a metaphor (as in indirect description) that points at the similarity between a woman and a pet, which is what carries the sexist aspect. No big problem with that, you can simply withdraw the “pet” part and find a term that actually points things out.
