Girl friendship drama

My friend A is friends with this girl B that I barely know (we’re all grown women btw, here you go drama).

I met B like twice and just didn’t feel the best vibes from her, so I never wanted to pursue a friendship. When I got to know that my friend A is now friends with B I told A about how I feel about the other girl. A can be friends with anyone obv and it’s not my business, but I thought I’d share since usually I’m never wrong with vibes that people give me. Since I don’t really know B, I didn’t have anything bad to say about her. It’s just a “feeling” that I thought I’d tell my friend. Nothing malicious or anything. Anyways I didn’t really care and A didn’t either.

Fast forward A told B that me and A spoke about B and what I said. I know, nasty move and A apologized to me. I know she didn’t mean it in a bad way, but it just slipped out and B took it suuuuuper personally, threw a fit and started calling me the worst names, which only confirmed what I thought about her.

Fast forward again (because all that happened like months ago), now B is mad at A because of “different things in their friendship don’t work”, and I am the main reason. B literally told A she shouldn’t be friends with me and that we’re playing besties. Besides the fact that A and I hang out maybe once a month if we’re lucky, B obv can’t tell A who to be friends with. So now A is laughing about it and very confused, I’m confused too but also like “I knew it girl” lol

I feel like last time I had these “fights” was in middle school lmao almost missed the old times
