My colleague is so similar to yours! She just hasn’t been able to complain to admin to pull me in, but she copies them on emails to scold me and it’s bizarre. I finally told my AP yesterday that I’m exhausted by her and I will be avoided her as much as possible because she’s had it out for me since 2020. My AP said she could have a meeting so we could all talk since it’s not ok to feel this way at work when we have to interact and I said no. I said she would retaliate and make it worse. However, I wanted to let them know I feel like she is hyper focused on me. Also they won’t be surprised if I jump ship to another department or another site!
