AITA for telling my lazy stinky monster fiancé she is disgusting?

I (clean M35) have been dating my fiancé (utterly gross and disgusting F33) for 3 years.

She used to care about her feminine cleanliness and womanly hygiene, but then she, being an idiot woman sheep, believed a TikTok that said following men's rules of cleanliness meant you were unhealthy and were going to die!

Obviously, she, being an idiot stupid woman, listened to the TikTok and now she FOCKIN STINKS!

I walk into our house every day and it smells like shit. Then i realize it's just my wife-to-be, looking and smelling like shit.

She works out?? even though she's a woman?? Right after work, so she's always sweaty and disgusting.

I can't even look at her, because she looks and smells like a Sasquatch now, so I sleep on the couch. It's been really hard for me and you should sympathize with me.

Eventually this foul! disgusting! monster! asked why I won't even be in the same room as her and I let it loose.

I calmly explained to her that she was disgusting, she smelled like a swamprat and her value as a woman had plummeted.

The monster, being hormonal and emotional, was upset and irrational. She told me I have to be patient? And "care about her health"?

The witch-monster was speaking in incomprehensible terms, so I calmly slapped her and told her she smelled like a bunch of sweaty men.

She asked me if I even cared about her anymore... to which I promptly and calmly responded no, because she as a woman has nothing except aesthetic value to me.

Now the monster is upset and she won't talk to me because I "hurt her feelings". Am I The Asshole for calling her disgusting and smelly and a Sasquatch?
