AITAH if I talk about past experiences with someone new?

I 27F have been working at my job for five years and I never had a problem with anyone until I moved locations. This girl 24F will call her Tiffany has been making look like a bully since I got there. When I first started there was already drama going on so I was trying to keep my distance until my name was mentioned in an argument between Tiffany and other coworkers. When I asked why my coworkers told me they have no clue. Fast forward to a few weeks later and someone got fired because Tiffany decided to email the manager ( who just so happens to be my mother) the group chat thread to prove that everyone was talking about each other all the time. I was being petty and I can admit that and told everyone what she did.

When the drama ended and everyone moved on Tiffany started targeting me. Tiffany likes pulling people to the side and talk shit about things you are doing wrong and her way is right. The first time she did it I let her have it. It was my first time in forever working at that location so things moved differently and I had to get used to it Tiffany was telling me that she felt like I was over stepping when she giving other people advice and I didn’t feel like I was I was just questioning it because I wanted to understand why it was being said and I know what to do next time it happens to me. Tiffany then proceeded to call the coworker slow by saying “she can’t comprehend too many things at once” then she added in the fact that everyone was uncomfortable with me because of my mother and they felt like she was going to show favoritism towards me.I was taking a back from that comment but I apologize and told her I appreciate her for tell me this and moved on.

Tiffany sent a email to my mom and the person above her about me and the situations that we were having. I thought we have moved on so I didn’t care about it. During the meeting she made look like I was bullying her and trying to make her look bad in front of the new person when it wasn’t the case. I expressed to her that she was being disrespectful towards me and she was icing me out. Tiffany said when she was approaching everyone to apologize for her behavior I was a non factor at that time. Okay ouch. At the end of the meeting I told her that I do not want to be friends with her because she showed her true colors and I didn’t like it she agreed on not being friends and that was that.

Today I was told that she sent out another email about me again. In the new email she was complaining that I was telling the new girls the drama between us and she feels so type away. Me and Tiffany has been only talking to each other when it’s work related and she is the trainer for all new employees so when she’s training someone she makes it clear that I am not allowed to tell them about any drama that has been going on during their training which I understood because it makes things toxic.

The whole time that Tiffany was training she told the new employees not to come to me for anything basically making it look like I haven’t been there longer than she has. It was to the point she said it in front of me. Tiffany was leaving for the day and she told the trainee to go to two other coworkers when she was doing her job I was sitting there and I asked Tiffany upfront why can’t they ask me and she said nothing like no words came out of her mouth. Instead she pulls the trainee away and told her to wait until tomorrow when she or the lead was there. Like wtf.

The trainee has asked me what happened between us because she feels the tension between us and I told her about the past situations and the things that I have done. I told her because I didn’t feel like I needed to lie because they already has come up to their own conclusions about Tiffany so I didn’t feel the need to hide it because she’s done her training.

AITAH?
