Boy tryna fight me?!?

So I was in town yesterday with my lil buddy as he asked me to come hang with him and his friend, I did. Another guy came on his lawn tractor(it's normal where I live) which was fine at the time. I felt alone so I asked my friend who wasn't far from us to come in too and she did, another 2 guys also showed up, they all played basketball and me and the girl just sat and talked. One of my bestfriends drove by in their new car, I went out to talk to her and asked her to take me for a drive and she said yeah. All the guys hopped in her car and she panicked. She yelled at them to get out, til they did, one didn't. He was in the front and thought he could stay there and come too. (For the record this guy use to bully me throughout school as long as I can remember) he wouldn't get out of her car and she looked at me knowing I could tell better. I told him he needed to get out of her car now and kept yelling til he did. When he got out he was like "Macy you're such a lil bitch" and pushed me back into a fence. I was lit. I ran at him and grabbed his hood to turn him around and punched him right in the side of the face. No one knew what to do because I've never defended myself before and that's why everyone always picked on me. He got mad I hit him and he grabbed me and threw me into the fence again, I was like no, I'm gonna show you how I feel about how you've treated me and used me for friends when you had none. So I dropped all my shit as he walked away laughing thinking he won. I ran fulls owed at him and smashed into him and started punching constantly at the back of his head since he wouldn't turn around, none of the guys there took up for me and just stood there. He even raised a fist at me. I told him to hit me and see where it got him, and he let go. If he hadn't of pushed me and he had let go of me when I had asked I wouldn't of punched him, but let me tell you how good it felt to defend myself for once, I got in my friends car and drove off with pride I wished I had sooner. We saw him walking around town later and all I could do was smile(:
