I put up with so much, Its been a year and I still think of him every day

I knew from the moment I saw him that I wanted him, he was charming and sexy and just different. He made me laugh He knew every detail about my life things I had never shared with a guy before.
When things were good they were great, when things were bad... well, they were really bad. All of my friends didn't like him, they thought I could do much better and were confused at why I was so smitten. I was just drawn to him and couldn't get out. He was online sites a lot, I knew but was too afraid to ever bring it up to him, I was afraid he would leave me. I found a blog he wrote critiquing our sex life, I forgave him within the night even though I would cry after every time after.
He ended up moving away, we were in a long distance relationship, he went to the bars every night with his friends, I stayed up states away and worried. What is wrong with me why am I so pathetic, I ended up breaking up with him, he yelled and screamed at me telling me I would never find any one better than him, I secretly believe him. I have been single for a year 23 years old with a career, but Im afraid of relationships. I still think of him everyday and miss him, it makes me so mad. How can I get myself to move on, why do I still care about him..... I feel stupid.
