Removing a Bridesmaid / Wedding in 2 weeks - Help!!

In a bit of a wedding crisis😢 We are getting married in just 2 weeks and I so badly want to remove one of my bridesmaids! The thought of having her there makes me not excited for my wedding day at all. Does this make me a horrible person to remove her last minute? I’ll go into more detail below but how the heck would I even politely remove her? I know if I remove her it will destroy what little friendship we do have, which I’m not *totally* against. We’ve had such an off and on friendship I’m lost….

I asked her earlier this year to be in it and she has shown so little interest in anything wedding related. Granted, I know she’s not the MOH so her “duties” were less but she didn’t help my MOH plan any of the bachelorette party, didn’t thank her to planning any of it, hasn’t offered to help plan anything, hasn’t offered much morale support, etc. I was her MOH and busted my bottom giving her everything and more for her wedding! She just now bought her dress 2 weeks ago and still has yet to get it altered. And on top of that she’s just not a good friend! She is never there for me through my good and bad, she never reaches out first if I don’t, she makes everything about herself, and as bad as this sounds she’s just extremely obnoxious and embarrassing to be around. She also has kids that are absolutely FERAL. I am a mom myself and love kids but can’t stand hers! They’ve destroyed my daughter’s birthdays before and more. I’ve made it clear to her she needs a babysitter the night before and the day of, and she said she “thinks” she has people to watch them. IMO you can’t be in a wedding AND have your kids with you the whole day. My fiance and whole family can’t stand her with a passion. It’s now to the point where my MOH without hardly knowing her doesn’t like her either because she very quickly picked up on the kind of person she is the few times they’ve been around each other. I have tried bringing all of this up with her a few different times this year. Once was about 8 weeks ago when I just bluntly asked her if she even wanted to be in it still because of her lack of interest not only in the wedding or our friendship. She gets defensive and has excuses each time.
