Moved into a toxic home

With all of the closures I had to move in with my boyfriend and his mother when my dorm shut down. I've been staying every weekend for close to two years so I'm not unfamiliar with how toxic and manipulative she is. But now that I'm doing online school and working, I have almost no time and while I'm grateful she is letting me stay here, she makes everything hell. You could do everything right and she will find something else to criticize you about. She always thinks shes right, has never said sorry in her life and uses generosity as a weapon. She will be generous and kind with her money and gestures but turns it around to make you feel like you owe her and you have to take whatever she throws at you without complaint.

Just tonight I had pulled stuff out to reorganize because I dont have enough boxes for all of my items i brought back from my dorm. After putting stuff in my car tonight, and knowing i was reorganizing she came up to yell at me and my bf about the mess. And you cant argue with her, at all. Ever. There is no winning.

She financially supports my bf bc he has health issues so we cant move out, and I have a job here and I'm 3 hours away from home. I have months left with this woman. My family is extremely supportive and wonderful, so while I had warning bc I've stayed here every weekend for two years, being thrown into this toxic household 24/7 is so difficult.
