AITA for taking revenge on my ex, ex bsf, and her weird ex? (#6)

This went on for two months and I started to feel insecure and upset about it, but I kept it to myself since he was busy playing games. By the third month of our relationship, my last straw was when he did a matching profile pictures with a girl. I decided to break up with him and he begged me to stay friends. So, I did because I loved him.

I REALLY did try to stay friends, but I started to feel uncomfortable and more depressed about it. Then not even two weeks, my ex-bsf was dating him and I didn't know what to say or feel since I was still into him and she knows that because I cry about him on calls with her. I was fulfilled with rage and made irrational decisions. I dated her ex, used him for information and exposed him to others how weird he was because he leaks photos of different people and him begging girls to show their midriffs for him.

After that, I finally replied to my ex's spam messages in my dms and read it only to realize that he was still into me. So, I just responded with 'Why would you date her then?' to which he answered with 'I don't know, she was forcing me to and I went along with it to cope my feelings for you.' and I don't know how to feel about this. So, we decided to meet up at the park around noon.

We sat on the swing as he confessed to me that he realized how much of an a-hole he was for taking me for granted and I just responded with 'I hope you know how stupid I felt for loving a guy who can't even spare a glance at me.' Then he cried on my shoulders after he jumped off the swing. I just sat there and pushed him off then went back home.

After I got back home, I confronted my ex-bsf in a call about her recent antics. She called me an a-hole for literally being upset about her dating my ex like she doesn't know I was still hung up with him. And then, kept calling me the n-word when she's white like snow. I then decided to expose her to our other friends that she was below 13 and my ex felt sick to his stomach.

We all didn't know that she was below 13 until her weird ex told me while I was forcing information out of him. Not only he's weird, but he's literally close to being a pdf-file since he was 17 that time.

So, yeah. She blocked me and I no longer stayed in contact with her. As for the exes, I kept them blocked and I've been thinking to myself after two years if I did the right thing.

AITA?
