Not sure where to start....

So, today immediately after i got home from work (11hr day most was spent on a roof in this bs below zero windy shitty shit), my wife said she is only taking care of things that belong to her in the house. Side note: We have small 2 kids and have been married for 12 years. She said she is no longer doing any laundry other than her own, only doing dishes that are hers ect. I understand she is not my mom, or a maid, I have no issue taking care of my own mess and helping out with kid messes. She has handled more of the house work and things for the majority of our relationship, mostly because I'm the one who has been responsible for ALL of our bills so I am usually at work for the majority of the day. Would it be acceptable for me to tell her that she is going to need to start paying for her car herself, half of our house payment, and half of all the other shared bills? Another little fun thing; she has also recently said we are no longer in a romantic relationship..... idk sorry this is a mess to read, I am a bit of a mess right now 😵‍💫🥲. I don't know what to do haha, I don't even know if I care anymore, kinda sorta over shit. Sorry for the ranty bs 😅

Tl;dr not sure if this is going to last much longer, idk
