How To Break Karmic Connections

I met this guy a year ago me and him weren't friends that long before we began dating, when I talked to him on the phone I felt nervous and got butterflies in my stomach. A couple of weeks later we broke up and I was sad. Me and him where still great friends and we still liked each other until a girl lied about me and broke us apart, then they began dating and he begin spreading rumors about me, I thought me and him will make good friends because I am a leo he is a libra. I got sick and tired of the rumors and I went to a new school school. 10 days later he called and apologize about being a jerk so he asked me back out I said yeah we dated for a couple of weeks until I made a rude joke he took it as offensive and he broke up with me, I apologized but he didn't forgive me and we never talked again. A year later I still think about him and miss him. I wonder if he was my twin flame because I had a dream about him before we met and to this very day I still dream of him and I can't let him go. I heard that if twin flames aren't ready to reunite they will separate. He was my first love and I want us to reunite as friends, but a couple days ago I figured out that he was a karmic relationship, it been a year and I still can't stop thinking of him. So I decided to break the energetic cords between us I tried visualizing the cords so I can break them but I can't visualize because my third eye is blocked.It's like I try to stop thinking about him but he keeps popping up in my head and in my dreams and I am confused about how I can move on I want to move on so I can feel free. How can I break the cords without visualizing?
