Hey so I need some advice on if I handled this the wrong way. So I have this friend, her name is Bella and we met on the first day of school. I was the new girl 🙄😂. I met her in the lunch line and we've been friends ever since tonight ig. Bella's been starting to act differently and I wasn't really feeling the vibe she was get from her. She was having sex with this guy with a gf (but justified it saying its not her problem bc the gf won't brake up with him), she would sit at our lunch table with our group of friends and have in headphones and only take them out to listen when there is drama/tea. I'm just over it. I feel like I'm better off is not being friends anymore so I texted her this (picture attached). I did come off a little harsh but honestly it's just my emotion shown through text. I want her away from me altogether. Do you think this was wrong of me to say?

I called her and she said she's very sensitive and bipolar and sometimes she just doesn't want to talk. I called bs on it bc EVERYTIME I see her she's all laughing and having a good time. I'm literally just over it. Am I being a bitch or is it okay for me to cut out toxic people from my life?
