My friend might've liked me and now she's married/E-dating on discord

SO this was 2 years ago, and I have a friend ill call.... Sadyia, I became her friend at a dark time in her life and we did get along and she was introdouced to my friend group, and she DID NOT like them, always making back handed compliments to all of them besides me (she does it to me now but wtv) and not only that she was always love bombing me, and would SPAM me  but ofc I was a people pleaser so I would always be afraid to tell her to SHUT UP,,, so one day I talked to one my homeboys at lunch ill call  Ben abt it at lunch and I think one of sadiyas friends, ill call L heard, cuz sadiya started ignoring me and started being a BITCH,,, and L would EXAGGERATE everything. And then Sadiya started bugging Ben, AND another homeboy ill call Sally. and I just stopped talking to sadiya after she called me a guilt tripping hypocrite over food. and RN she's online married to some1 on discord and added that same persons number into our MESSAGES GC meaning she trusts some1 she found off PINTEREST (She made a promotion for her DC server off Pinterest.) AND GAVE HER, HER NUMBER,,, and she trusts that online friend more than ANY OF HER IRL FRIENDS. so though I may have fumbled, How do I tell her this isn't healthy to do??
