<human>: Give me the gist of the text in a nutshell

I recently moved back to my home town. I was looking forward to seeing my old friends from high school; most of whom I had kept in touch with. 

However, since I moved home, they've stopped talking to me. I had tried to throw a holiday party and invited them with the thought that they'd come and it'd be like old times. At first they were really excited about coming, and then they all declined. Since then they haven't talked to mech at all. I asked one of my friends what happened and why they were all avoiding me. He said that it had to do with Abby.

I was confused for a moment, because I know a couple people named Abby (I changed her name her of course blah blah) anyways, when he told me which Abby, I wanted to laugh.

The background of Abby and I was that in high school, she dated a one of my exes. I had never met her. The only interaction I had was when she threatened me over myspace (I was 16 I think) to stop being friends with her boyfriend (my ex). I responded rudely. Later my ex came to me with her sob story that I bullied her and was telling her that I was going to steal him back. I sent him the conversation and he ended it with her.

Well turns out Abby is dating one of my old friends now. When she found out that he was friends with me, she was livid and told him that I bullied her in high school. The guy texting me said that he could hang out with me when Abby and her boy friend aren't there. He said that the others probably weren't talking to me because they didn't want to make her or her boy friend mad.

I have never met this woman in real life and I'm stunned that she has allowed her grudge to continue this long. I'm hurt that my "friends" would be totally fine with cutting me out of the group because of something petty in high school. 

Is there any way I can get them to be my friends again? I want them to know my side of the story :(
<bot>: Girl hates me because petty drama (that she initiated) in high school and it forbidding my friends from spending time with me.
