Why is she ignoring me?

She ignored me when I was after her in school. And when she came back, I ignored, just to let her taste her own medicine.

I was bit rude and cruel and possessive as well even though she wasn't my girlfriend. I tried acting cool. Last of the straw was when she left me for a threesome (as she said). I was totally against anyone having her body. We had a heated argument and it was over.

last day we met. I saw her but didn't feel talking. She was straight up ignoring me. Not even looking at me although I was at her arms length.

Now she joined my firm as young lawyer. She straight up ignores me even though we sit next to each other. I also heard she is dating a rich guy as said by her reporting manager. Also most guys are into her as I hear them discussing about her in the dinning area or loo.
