Girl's Behavior

Wondering why this girl acts so ad and upset with me? She seems mad at me? What does she think of me?

Thanks for taking the time to answer this. So there is this girl 24/f who I have somewhat of a history with. I Cursed her out many years ago like 12 years ago and recently I saw her at this party. I recently tried adding her to fb a few months ago and she didn't add me or allow me to rerequest her as friend. I was hurt and decided to block her and not have anything to do with her anymore.

I recently saw her at this party 3 weeks ago and I just basically ignored her. She ignored be back. When it was dinner time, she sat at the same table as me with her friends, I was with my own group of people. Whenever I talked she ignored me, but whatever. Eventually there was a picture that was uppose to include her, and I didn't want to be in that pic.

The next day, I ignored her basically, and she was about to sit at a table with her close friends, but when she saw I was going to sit there too, she just immediately moved to another table, but with her other friends, not super close but still her friends.

I mean I have the feeling that she felt it was awkward around me or was hurt I was ignoring her? I don't know. But I don't know what else to od, There is so much that happened ebtween me and her that I don't want to talk to her or anything, yet she is acting in response to me ignoring her.

I have the right to ignore her and not talk to her, but why is she showing that she doesn't want to be around me openly? Look I know she can do what she want and so can I, but why make it so obvious? Why is she doing this?
