Setting Boundaries with My Mom

so two weeks ago my mom said she wanted to stay the night tonight, but neither my husband or I are comfortable with that, so I told her no, I sent a boundary, now she's being petty and just refusing to come over at all. I'm fine with her visiting, but she can't stay the night, my husband works this weekend and having her here over night would disrupt our schedule too much. she seriously got upset because I set a boundary. when I told her that she can't stay because my husband has work, she replied with "I'm coming up to spend time with you" as if this isn't his home, as if we don't live in a tiny one bed one bath apartment. her being here would disrupt not only mine and my dogs routine, but it would disrupt his weather she talked to him or not. I don't know why she dislikes my husband, she has it in her head that he's going to hurt me some day, either physically or emotionally, yet she lives with my sister and brother in law and they argue all the time, my husband and I have never had a real argument in the 7 years we've been together. I get that she had a shitty choice in men (she's divorced 4 times, and is still single) but that's no excuse to treat my husband the way she does. she treats him like a parasite, just a guy who's job it is to take care of me like I'm a child. I'm so tired of the constant disrespect she gives my husband, yet when I try to start that conversation with her, she insists that she doesn't dislike him, she acknowledges that she doesn't treat him like one of her own kids, and that'd be fine if it were true. she's always saying things like "he isn't taking care of you" or "you're always welcome to stay with me, but he isn't" and that hurts because I love my husband more than anything and she just sees him as a constant threat, he's never done anything to hurt me, her, the dogs, or anyone. I just don't know what to do about this, because at the end of the day, I'll choose my husband over my own mom. 😢
