What did I do wrong????????!

I just wanted some space to myself. I did not talk to my best friend for a few weeks because I was dealing with a heartbreak so I wanted to be by myself. I gave her a notice that I am going on a hiatus for a few months, and she got angry at me. She kept saying, "How would you feel if I did the same thing as you?"
The strange thing is, if she did this to me, I don't feel offended. I respect people's space, why can't she do the same to me too?



So we got into an argument, and I was getting tired of her controlling me so I told her that maybe we should be acquaintances instead of being best friends as I felt too suffocated by her.
And, knowing the fact that I have trust issues, she use this to insult me and said that I would never know the meaning of a true friendship and I would never have any true friends in my life.
I have stopped talking to her since then. I am not angry with her, just felt that this friendship is too unhealthy and toxic.


I looked at her facebook, and I realised that she joined this fanclub called, "Call yourself a friend? You are the biggest bullshitter I ever know"
I am wondering, what did I do wrong in this entire friendship? :(
