AITAH for cutting off my mother?

For context:

I (22F) want to cut off my asian mother (56F), she has a husband but he lives in France while we live in Canada for the time being. She wanted to wait until I graduated (less than 5months) and got a job to move to France. However the last year living with her has driven me insane, she pressured me into a 52k car loan for the next 7 years because she at first “wanted to give me a graduation gift” and that explanation later turned into “i wanted a new car” after I lightly nudged the idea to her that I can’t afford a 1200$ monthly car payment. On top of when she moves she wants me to keep our 1500$ apartment and send her money when she moves to France. (because she needs an address to come back to every 6 months because of Visa rules) She talks to me as if I am some sort of investment for her to control and our history isn’t great either. She’s had CPS involved for child abuse when I was younger and I’m adopted, and though we have NEVER talked about these issues or the past we have been living together just fine. Her husband will be coming to live with ‘us’ for 6 months after she comes back from her trip to France. Also I cannot transfer the car loan to her because she missed 22 car payments on the previous car. (It had a 5k lien left on it) and right now we share ownership of the current vehicle so I cannot do anything legally without her consent, same goes for her.

However after the car loan decision, and her strong encouragement to “keep my options open” while I already am in a happy and loving relationship just because shes homophobic, on top of her spending Christmas in France with her husband while I have to spend it alone working and looking after our cat and dog, every little thing has built up. I’m not entirely sure if upping and moving out to live with my girlfriend and telling her I refuse to pay for the car anymore would be an asshole move? My main concern is how she is going to get to work even though that wouldn’t be my problem, I still care, and she’s still my Mom. I don’t really know. I’ve been trying really hard to convince myself that I have to put myself first and my safety and well being but at the same time mentally I feel as if I owe her my life for some reason.. I myself have been struggling mentally lately and have even started getting counselling for myself because of all this pressure.

Things I worry about if I go through with this: •Afraid she will use the animals to guilt trip me to return. •My Safety when being alone in a room with her. •That she may get depressed and lose the apartment herself/won’t be able to get to work

Am I the asshole to get up and leave my financially struggling mother to live with my girlfriend ($300 rent) so that I can save money to hopefully have a better life for myself? Or am I making a mistake by moving out because I pay no rent at the moment?

Long Answers are very much appreciated. Please tell me how wrong or right of a position I’m in to make this decision.
