She mistreated me for years now she wants to reconnect. What would you do?

Long story short many years ago I asked a colleague out and she rejected me.

I was okay with that and not even awkward, but she started to mistreat/bully/gaslight me and I couldn't react because if I did I was the desperate resentful rejected guy to colleagues' eyes.

I had to endure this for years, I'll keep it short by saying I was a worthless piece of trash to her that she could use as her punching ball.

This took a heavy toll on my mental health, one day I even apologized because she was angry for something and in return I got a long message on how I was misreading everything and she was not into me. The day after she told that to the colleagues and someone hung at my desk a book quote about not understanding when it's time to stop.

At that point I decided to delete her from my life, mainly to preserve my remaining sanity. I thought she would have been happy instead she was extra pissed at first, she tried to provoke me, then she ignored me back.

Luckily I was moved to another work team so I totally got rid of her and started my years-long healing path.

I was doing great without her but recently she started to desperately want my attention. Trust me on that, she's explicit and I can't misread this since I'm ignoring her and she openly stares at me and a couple of times she even followed me outside work but she never had the guts to talk to me (she had them when she considered me trash) and I'm not going to facilitate her.

So questions are: did she realize the pain she put me through or am I just her last option after the many guys that got served first and left?

Obviously a relationship is not on the table and neither is sex but would you bother reconnecting as acquaintance?
