a question?

Hi

I wanted to ask something because I'm unsure. I followed a girl like that on her main account and she followed me back and then she created another account and followed me and of course I followed her back and suddenly she changed her second account and it said on her profile (only for cool people) and she removed me. By the way, I also have a second account and she followed me from her main account there too and I removed her from there, but she didn't remove me from her main account and I don't know, should I remove her from my main account? because I don't know.

I hope you can understand this because I tried to explain it to you well.
