Alright ladies, I am in desperate need of advice on how to handle this crappy situation. I am at a loss on how to do this in a direct but compassionate way because subtlety is not working :/
I became friends with a coworker (like having dinner once a week and almost always eating lunch together at work, hanging out on the weekends, buying each other christmas gifts) and I thought that things were all good. To preface this, I knew that there was some tension between her and our team lead. This tension stems from our lead getting the position over my friend- which my friend says hurt her because she didn't know the other person was applying and they had been friends. Now the other person tries to avoid her and limit interactions which seemed a little mean to me. My friend would make comments to me or vent and it became clear that she is still bitter over not getting the position, but that feels somewhat normal? (it has been a year or more since the choice was made, for context.) She seemed to be on okay terms with our other coworkers, aside from the fact that they are friendlier with our lead.
In January/February, my friend was talked to twice by our supervisor who had 'heard through the grapevine' that she had a problem with our lead and had been speaking poorly of her. My friend denied this, and said that our lead was the one who had been icing her out. She vented to me about both meetings.
In March I learn that there were specific comments that led to her being talked to by our supervisor. She had been training with someone in a different department (someone she was also friends with) and had begun speaking very poorly of everyone in her department- including me. Saying we are all too immature, we don't do our work, we have too much free time, we're always on our phones, overall we just aren't suited for our jobs. The person training her was so upset by this that she ended up telling our supervisor and requesting to never train my friend again.
Needless to say, I am pretty hurt. I had considered this person a trusted friend. I've babysat for her, we've spent so much time together, I tried my best to be there for her when she was struggling. I don't understand why she included me in these statements, let alone why she included all of our coworkers. None of what she said is true- we are busy *all day* at least 4 days a week, not counting when we go to help out other departments. Yes we are all 10+ years younger than her, but does that make us immature? We're all working at the same place, doing the same job...
She has been acting like nothing has happened and I have been slowly distancing myself. Choosing to eat with other people outside of the lunchroom (we are afraid that things said in casual conversation will be twisted and used against us by her), saying I haven't been in the mood to socialize much, limiting our interactions as much as possible. This has resulted in her pressing harder and harder for me to hang out (seriously though, what part of someone saying 'hey i've been feeling burnt out socially' means you try guilting them into hanging out with you multiple days in a row???) and glomming onto me at work. If she sees I'm somewhere talking to other people, she comes and inserts herself in the conversation, which promptly dies.
I have spoken to our supervisor about this, essentially just informing them of the tension in our department and imploring them to try and do *something* to help alleviate it. But I am at a loss on how to handle this on a personal level. I don't want to be mean or cause more problems with her, but I can't handle her clinging to me like this as if nothing happened. My current maaybbbeee plan is to find a time to speak to her face to face, but how do I frame this?? What do I do??? Please help me :'(
