Would I be an asshole to not invite my mom to my wedding

Me and my fiancè are getting married in the summer and I honestly do not want my mom there. My mom and I have issues. She's the type of parent that loves to throw in their face all they did for you when it's really what they are legally required to do. Like boohoo you fed me. You didn't you go to jail for child abuse so what's your point? She never acknowledges the things she's done that were bad and when it all comes down to it, she was not a good mom. There are 4 of us and she doesn't even have custody of my youngest brother. He's 13 and living with our grandparents and when they pass away he's going with my brother and SIL. She's also shitty to my fiancè. She's never liked him and for absolutely no reason. He's never done anything to anyone and she almost killed him at one point because she was ordering food to our home and I told her to make sure whatever she gets doesn't have peanuts because even being in close proximity to peanuts causes a reaction. She thought he was over exaggerating and on purpose ordered something with peanuts and he had a reaction. Had to administer his only epi pen and went to the ER. She apologized. Lastly my two adult siblings are married and both weddings my mom ruined. My mom showed up not only in white but in an actual WEDDING dress to my brother and SILs wedding and threw a tantrum when my brother wouldn't dance with her first. Then got drunk at my sister's wedding and ruined it by acting a fool. I don't want her at my wedding. I know it will hurt her feelings but she can't handle not being the center of attention and I know she's gonna ruin everything
