my heartbreaker

first, I thought everything was going smoothly and efficiently. I was freaking happy and excited. I loved him to the bottom of my heart. I think about him everyday and every time he's the only on my mind. We broke up, I still feel the same thing twice than the first one. Was it something I did or that he didn't love me anymore. Every time I try to forget his face, I only see his best smile. When I hear his voice, my heart pounds. I get mesmerized when I look into his deep brown eyes. Is it okay if I get jealous when I see him with other girls? I cry most night because of him. I cant stand it if I see him sad, even when we broke up. I feel the urge to go and comfort him but I restrain myself.
He was my first love and heartbreaker. I love him till this very day.
I still don't know why he broke up with me and I still seek the answers.
