A very close friend [both F36] who screwed me over 6 years ago wants to get "friendship back on track"

I don't want to go into to much detail because it still upsets me. Basically we were inseparable and i was so good to her. Another friend in the social circle started spreading lies and she believed them and basically spread it around, what the lies apparently were is irrelevant now but it absolutely broke me and led to my whole circle abandoning me except for the 1 or 2 close friends that believed my side and stuck by me. Despite these couple of friends i went from having an active life with meaningful relationships to having to sit in my house all the time for fear of what was being spread.

Even to this day it upsets me simply because how long, great amd strong these friendships were.

Fast forward to New Years Eve just gone, on a night out i bumped into her boyfriend who i was also close with, lots of drinks were had and the last was bought up and he was saying how silly everything that happened althouhh nothing was mentioned up until just yesterday and it's properly fried my head. A text off a number i didnt recognise saying "Hi, you've been on my mind a lot lately and wondered if we could get our friendship back on track? x". Through a bit of research through other people i found that it was her number.

I just don't know what to do. Shes still close with the guy who originally spread all thise rumours too. She hurt me so deeply and dont think i can ever forgive and forget. Obviously i miss her but she contributed to completely destroying my life mentally and socially. My mind is all tangled up right now and i've been a little tearful over it. Please offer me some advice/thoughts/anything. I haven't text her back yet.

TL;DR: A very close friend screwed me over destroying my social and mental wellbeing years ago and now she wants back in.
