Ignorant friend

Ok so like theres this one friend I currently just met back in December 29 2024 or something, 

My best friend who I was friends for 2yrs introduced me to her. 

I don't wanna say her name but let's just call her wind, so wind wasnt ignoring me when I first met her, she was like very kind and very caring. 

But after new years, she became very ignorant to me and it is rlly bothering me very much cuz she was taking all attention to my other friend, let's just call her island. Island is pretty much my bestest friend ever and agrees with me, but actually she met wind cuz of her au. Wind was ignoring me all the time, not even a single chat of me. 

Afterwards, I became so uncomfortable with her and never opened up to her

I just wanna know why she was ignoring me after new years, 

Someone please tell me why/ur theory or smth idk
