Should I give my Ex-Best Friend a Chance?

Hello all.

I really need some advice. I’ll start from the beginning, my ex best friend and I have been friends for almost 6 years. She’s a very high strung person, but generally we got along very well until I got a boyfriend. My boyfriend goes to the same school as her, so they’re friends as well. I actually met my boyfriend through her because she said he was a nice guy, so me and my bf were friends forever until he asked me to be his gf.

Anyway, about 2 weeks ago I announced to her that me and Jason(boyfriend) are together. Her reaction wasn’t exactly welcoming. At first she was like she already knew we were together. Meanwhile we just decided about an hour ago to become a couple prior to talking to her. And then she was like,“I know how this is going to end, but I wish you well.”

I told her that was very rude, and then she got mad saying im being rude for not accepting her honest opinion, that she doesn’t want to hear anything about my boyfriend and I’s relationship, and that she’s always right about predicting relationships,etc.

I was like whatever after that, and then the next day she posted on Facebook a song about a friend she wished well and didmt want to be friends with anymore. I put two and two together and it was obviously about me. She then deleted me and my boyfriend off of Facebook and told my boyfriend I was mad at her. Meanwhile, she’s the one that deleted me.

I texted her and was like stop lying to my boyfriend. She wrote back telling me again she wished me well but she doesn’t want to hear from me ever again.

A week later from that text she send me a message via facebook saying she wanted to talk face to face, but she never apologize. She sent a similar message to my bf but apologize to him.

I’m sorry for the long text, but this has been on my mind for days. I just don’t know if I want such toxic behavior around my relationship or around me for that matter
