I need help! Mom or boyfriend???

Malori
This is gonna be long! I met my boyfriend a few months ago, and things have been going great. I am 31, have my own home and my mom stays with me because she watches my kids and helps around the house due to my demanding job. About a month ago, my boyfriend started spending the night over my house. He lives 1 hour away, so it was easier. He drives me to work, due to a medical condition i cant drive, so prior to this, my mom would drive me. He picks me up, helps with my kids and all of that. My mpm and him have gotten along and things have been great. Until yesterday. My mom has been slacking on the housework, which i dont mind, but she wont let anyone else do it. For the past few days, all the dishes, and i mean all of them, are dirty. On multiple occasions, my boyfriend and i have offered to do them and even started them and she flips! Well yesterday, my boyfriend and i go grocery shopping. We come home and are cleaning out the fridge. She walks in and asks what we are doing and we tell her and she throws a hissy fit! Starts calling my boyfriend a motherfucker, he needs to stay out of the kitchen, she was going to do that. She starts telling me she is leaving and i better find someone else to watch my kids. My boyfriend goes out to the car, as he felt disrespected and didnt wanna argue. My mom still was inside yelling at me. Telling me that he is trying to move in, that she is embaressed by the kitchen, but she wants him to stay the fuck out the kitchen, that hes mister fucking know it all. Then shes like well im not leaving, im gonna stay and make everyone miserable. She went down in my basement, and i gave her awhile to cool off. I went down to talk to her and she was crying saying she is just embaressed. I calm her down and all seems well. Me, my boyfroend and kids leave to go to a friends cookout. When we get home, we all go to bed. This morning thoigh it started again. I come down the steps with the baby and she starts flipping out about the groceries i bought. Saying i bought the wrong kind of spaghetti noodles, half the things i bought, i should throw away bc its wrong, i didnt buy pot roast bc the grocery stores meat looked old, but shes mad i didnt buy it. And then shes throwing her hairbrush and stuff saying that my boyfriend needs to be gone by the time she gets back from church. But this is MY hoise. I pay all the bills, its in my name. And then shes saying when she gets home, shes gonna do the dishes so my boyfriend can have a bowl. That she is gonna call my older brother to see if she can move in with him. I feel like she is making me choose... i dont know what to do. I love my mom, i love my boyfriend... please help
