When a girl gets increasingly aggressive for no apperent reason?

so this girl said i made her uncomftorble so naturally i apologized to her freind cause she wouldent talk to me and said please ask her if i can do anything cause i dont wanna lose her as a freind and i also politely ask if he could ask if we could still communicate other ways at her pace then a few days later she says to her freind if i come near her or talk to her she gonna put me in my place i realize im not perfect but did i do something wrong in apologizeing to her?
