Welcome to R-Slash, Am I the Butthole, where OP's brother gets engaged to OP's bully?

Am I the Butthole for exposing my future sister-in-law for bullying me in high school at a family event?

In high school, I used to be friends with this girl, Anika.

We were close until junior year when I discovered that she had been spreading false rumors about me.

However, even after I stopped being friends with her, she continued to make up lies about me and

made my life hell right up until we graduated.

We went to different universities and I'm in my mid-20s now.

My older brother, Carter, went to the same university as Anika.

Recently, he announced that he had gotten engaged to his girlfriend.

Our family was happy for him, but we were surprised at the same time since we didn't know that he

was dating anyone. He said that he would introduce her at an upcoming family party.

The party rolled around and guess who walked in the door with Carter.

Anika, I honestly thought that I was hallucinating and I felt sick seeing her again.

Carter left Anika with some relatives, then came over to me and asked to talk.

We went to another room and Carter explained that he had met Anika at a party and didn't recognize her,

but it was love at first sight. But after he found out her full name,

he realized that it was the same Anika who spread lies about me.

He confronted her and she claimed to not remember me or anything she did.

He let it go because he really liked her. He then pleaded with me to be nice to her

since she didn't remember what she'd done and she was a good person.

I just told him that I needed a moment to myself to process everything.

When I eventually went back to the party, I decided that I would ignore her.
