How do I get closure on all this stuff that’s happened between us?

Helloeriss01
A girl got promoted and came back to my job and was in charge.
We slowly started talking more and I found her annoying at first. She knew about my boy friend and I’ve mentioned we used to argue a lot and I think eventually my relationship started to bother her. She was single but one day I wasn’t talking to her and she kept asking why I wasn’t talking to her and that I could tell her.
once my boyfriend sent me a pic and she snuck up behind me and jokingly was like “what are you doing?”
Also she kept getting me in trouble for calling my boyfriend and texting him and once flat out rudely told me to hangup on him.
She knew I was mad at her and would try and talk to me sometimes. We’d joke and I would tease her about her height because she’s taller and bigger and I’m petite. We’re the same age. She compared my height to an oversized stuffed animal and I got offended then she playfully touched my arm while laughing.
She also tried to make up by giving me a reusable bag from the job but turned around and got me in trouble for my phone again 2 weeks later.
I was upset about a customer one day and she told me she cared about me twice while we were alone.
She’s never asked about my boyfriend and got quiet when I mentioned him but has asked other coworkers about their relationships.
She got transferred again and on her last day took individual pictures with everyone but she grabbed me and hugged me and she didn’t hug anyone else.
I’m rlly close to this other manager and she knows.
The other manager told me that the girl would always find a guy when she went out and would text random numbers at work.
She has a boyfriend now and they’re getting serious and moving in and my manager asked if they’re getting married or having a baby and she got rlly defensive and said no like she had no intention of doing it. She knows word would get back to me. She still visits.
If she was always on her phone and trying to find someone why would she get me in trouble?
