AITA for ignoring this friend because she told me some gossip?

I met someone last year in a walking club through a mutual friend. We only hung out once, and then she added me to a group chat of a Halloween party. She pretended to be so close to me when I don’t know her that well. She invited me to her friend’s Halloween and gave me a heads up by saying her friend didn’t have a good first impression of me, so I should be cool at the Halloween party. I already felt pressured by that but decided to go since I already had an outfit and nowhere to go.

During that Halloween, I tried my best to go because I don’t usually drink or party. When I went, everything was cool, and her friend was super sweet, and she hugged me, etc. I left early just because they were drinking all the time, and I was tired.

Almost 7 months passed, and the first friend asked me if I wanted to hang out. I agreed, and after we met, she told me she’d invite me to her birthday party. I initially agreed to go, but she then told me her friend (who hosted the Halloween party) said I’m a bitch and looked boring like an auntie because I didn’t drink or dance. And I smelled bad and not to invite me anymore. She told me she’s only telling me so I can work on myself and it’s good to know what others think of you. I was shocked because I always wear perfume, so I felt bad, but maybe because I was out for 2 hours just to attend this Halloween party.

I found that so weird because I’m kind and don’t know any of these people well enough to have strong opinions about them. I also don’t like to gossip about others and would rather not know what they say about me, whether it’s true or not. I also felt suspicious about this girl because she started trauma dumping and telling me how she doesn’t have any friends and was calling other girls that I know “bitches” when I know they’re so kind and respectful.

She texted me as if we’re best friends and invited me along with 25 other people to her birthday. I felt like I already have a lot of friends, and I genuinely am not close with this person to involve myself in some drama, so I stopped responding.

She just messaged me asking if everything is okay and I’ve been ignoring her. I don’t want to confront her because she’s not an important person to do so but I also feel bad because maybe she actually likes me. Am I the asshole for ignoring her? I genuinely just want to block her but don’t want to hurt her feelings.
