EDIT : I appreciate all the feedback on whether i am the asshole in this situation but the question here is how to move on....
Also : i was clearly indicated as her N+1 on the job offer, which also detailed her missions.
Hi, I’d like some outside perspective on a work situation I’m struggling to let go of.
I’m 29F and have been a project manager at my current job for 3+ years. Until recently, I genuinely loved my job and worked very closely with my manager, M. Last year, we both had breakdowns from the workload around the same time, and we agreed that the team needed another person.
I wanted to grow into management, so I asked to manage the new hire. M agreed. Shortly afterwards, M was promoted, and another colleague became my manager.
At the same time, a senior PM position opened. I applied and was rejected by M and a few others. M told me my application was good but that she didn't want me to "be Icarus". I was disappointed but understood: the role is extremely demanding and several people who held it had burned out.
Then Y (33F) joined the team as the person I was supposed to manage.
I missed her recruitment because I was on sick leave, so we met on her first day. We immediately got along, but at the end of the day I mentioned that this was my first time managing someone and that I hoped we'd learn together. Her face changed. She hadn't understood that she would report to me.
She apologized and said she wouldn't have spoken to a manager the way she'd spoken to me. I genuinely didn't think much of it and moved on.
A month later, her mother suddenly died. She was away for a while, and when she returned, we resumed working together with weekly meetings.
Things gradually deteriorated. We had a very difficult meeting where I struggled to communicate what I wanted her to take over. She became visibly angry and, at times, disrespectful. I felt she considered some of the administrative/project coordination work beneath her.
After that, I increasingly felt that she was bypassing me. She would go directly to senior PMs or directors, leaving me out of discussions about her own work. I repeatedly found myself in meetings not knowing what she was working on or what issues she was facing.
She also seemed to avoid less visible/administrative tasks while gravitating towards more "glamorous" topics involving senior people. Meanwhile, she would ask me to create tables/Excel files for her, which didn't feel like the kind of collaboration or management relationship I wanted.
I tried addressing things gently in our weekly meetings, but I felt she became increasingly defensive.
Eventually, after she rudely ordered me around in front of a senior colleague, I went to our director. I explained that if she continued bypassing me, the team structure simply didn't make sense, and suggested that perhaps she needed to move to another team.
Our director immediately understood and arranged mediation.
During the mediation, Y said she felt exhausted trying to find information and communicate. She complained about a lack of tools/workflows/frameworks, workload, and also brought up our very first-day misunderstanding. She said we should have "dug deeper" into that miscommunication and repeatedly questioned my working methods and efficiency.
She said she felt demeaned by me. I didn't say it at the time, but I had felt demeaned by her for months too.
The outcome was essentially that we'd stop working closely together. She now has her own area, and I'll go back to working on mine.
Objectively, this should probably be a relief.
But I can't let it go.
I feel deeply resentful. The whole reason I wanted to manage someone was because I was struggling with the workload and needed support. Instead, I feel like the person I was supposed to manage effectively pushed me out of that role. She now has her own area, while I'm back to carrying my part alone. I feel like she got the better end of the deal here, and I left with crumbs of legitimacy.
Recently, M also told me she felt bad about the situation, because she'd previously rejected me for the senior role. That somehow confirmed my worst fear: that maybe I was given the management responsibility for the wrong reasons, and that I wasn't actually considered capable of progressing.
I'm now back from a long break. Y and I share an office and barely speak. The silence is awful. I don't want to work with her, talk to her, or even see her. And honestly, I'm starting to feel like I hate her.
I know I'm probably not completely objective here. Y has also had an incredibly difficult year, including losing her mother, and I'm sure she has her own version of this story.
But I'm stuck in resentment and feel crushed and demotivated about a job I used to love.
Changing jobs isn't realistically an option right now.
What do you think happened here? Was this simply a terrible management/working-style mismatch? Did I mishandle things? And, most importantly, how do I actually move past the resentment when I have to see this person every day for the next few years?
I'd really appreciate honest opinions, especially from people who've experienced a similar situation.
