Overwhelmed by my mother?

few years ago, brother adopted a dog and dumped her on my mom and I. I moved out a while back with my partner who had a smaller dog and we couldn’t take the other dog anyway because neither are dog friendly, and there is no land for her to run. She expects me at the drop of a hat to come over to her apartment for several days at a time and then will extend her trip to visit my brother and his family, completely disregarding that I have a life of my own, and then either guilt tripping, being passive aggressive, stonewalling. This has built up much resentment because she continues to enable him and let him do as he wishes to. Now, she’s moving. Over an hour away from where I live. Before it was 45 minutes. She’s asking my partner, and I about helping her to move, but will not tell us when and expects us to do it on her time when we both have jobs. when I had brought this up to other family members, they defend her saying that she’s older and she’s alone. I don’t think that’s an excuse for her behavior. She completely disregards that I have a life, and she constantly depends on my partner and I to help her do the smallest of tasks. for example, yesterday she wanted us to pick up the dog and bring her back to the apartment which was four minutes away when she was supposed to come back the next day. (spoiler alert she once
extended her trip). Now with her talking about the move, I am beyond overwhelmed because I’m not understanding why she can’t ask her son to help, & I feel like this is all falling on me and I am completely overwhelmed like I just want to cry. And nobody understands how frustrating this is.
also, she’s Catholic. My partner and I are planning to wed, however that’s a problem too because again she’s a devout Catholic and she thinks that one denominational wedding is the only way it is supposed to be. my partner is of a different denomination. i’m literally having panic attacks thinking about this because I feel like she’s just going to pitch a fit.
