should i cut my best friend off

im not sure if i should cut my best friend of or communicate my problem withher, cuz she might not understand. i struggle with confrontation a lot so i need some advice. my friend keeps on ghosting me and switching up (via text; were long distance atm) ik she doesnt owe me anything in conversation, but shes constantly is either really passive agressive and distant or super friendly and close. her eneegy comstantly feels like its draining me no matter which mood shes in. whenever i hype myself up or anything she gets rlly weird and acts like im obnoxious. ik she has a lot going on sometimes but so do i. she also ghosted me om whatsapp recently for weeeksss but comtinued to send me videos on insta. she constantly leaves me in the cold and it gives me a lot of anxiety amd confusion. i wamt to protect my peace so idk if i should js cut her off or try to talk to her. helppp
