Is it normal i don't miss the best-friend whom i cut contact with?

About 16 months ago, I was forced to switch schools due to the way I was treated by my teachers and classmates. In doing so, I was faced with the realization that I now had the chance to do something I'd been wanting to do for a very long time; Cut all contact with my then best-friend.

It might seem odd to have someone say that, but believe me; I had my reasons for wanting to remove her from my life. Since the start of our friendship, she always seemed to want to put her friends into two categories; me, and all her other friends (Which were all in one group). Whenever she'd hang out with me she'd never tell the group, and whenever she'd hang out with the group she'd never tell me (I even recall her getting mad at her mother when she asked me if I prepared my backpack for a trip to the beach that my then best-friend and her group were going to make). She was also very rude and liked to play the victim whenever she I would call her out on her rude behaviour.

I know this makes it seem like we never were true friends, but at the same time, we told each other everything. I was one of the first people she'd trusted with the fact that she was bi-sexual, and we would talk all night and day about all sorts of things we agreed to never tell anyone else about.

Over the summer of that same year, (Again, after switching schools) she just seemed to get worse and worse - she wouldn't reply to my messages and when she would they'd be one-word responses, I would hear about all of her secrets through a mutual friend (Who is now my current best friend, ironically) and no longer from her, and we almost never hang out.

I was also being prosecuted by her A LOT over my sexuality. I'm homosexual but I'm still not open about it and she seemed to be angry about it, so, e.g., she'd show me a picture of a male model and say, "Oh, and by the way, he's gay - just so you know," in an extremely irritated tone. The random outbursts she'd have and the way she'd subsequently play victim became much more common.

In the end I could no longer handle it and stopped talking to her all-together. Blocked on social media, on mobile, on everything. Our mutual would try and convince me to talk to her but I'd always say the same thing; "Planning on it," (But of course that was my way of saying, "Not gonna happen,").

We had a huge argument which lasted over 30 hours of constant messaging before I just stopped caring. I remember the last time I talked to her was when I told her I couldn’t go to her birthday party.

I don't miss her at all, to be honest. Though I only really have 1 person I can call a true friend as opposed to 2, I'm happier. I do get lonely sometimes and am extremely tempted to send her a little "hey!" I know what's been done has been done and I need to move on.

She tried to come in contact with me, and told me she misses me, but I honestly don’t.

Sorry if that was a lot to read, by the way, I always ramble on when it comes to backstories, I love remembering things even if I'm not very fond of the people in memories.
