Leaving a parent out of your wedding

So, my mother. We recently went more than a year and a half without speaking after she told me to drop dead. The relief of not worrying about dealing with her was tremendous. She started calling occasionally a couple months ago and is now up to about twice a week. The conversations are short and awkward. She started calling more only after finding out I’m engaged. One the one hand, it seems like she’s trying to form some sort of relationship. On the other hand, she could just be angling for a wedding invite so she can make it all about her. It’s a special gift she has, taking other people’s special occasions and making it about her. I haven’t seen her in nearly nine years. She hates my Dad with a fiery hot passion, and he will most certainly be there. She dislikes my aunt & uncles too, who will likely be there.
So when I type it all out, it seems obvious-don’t invite her. But my hesitation is this-isn’t leaving a parent out of your wedding pretty extreme? Like, a relationship doesn’t come back from that. It seems like it would be a very final thing to do, and that unsettled me somehow. But at the same time, worrying about her interactions with my Dad and we’ll, frankly, everyone, indicates I don’t want her there. Thoughts?
