Do you find something not right about this guy?

There was a man who was 2 years older than me. Who I was myspace friends with. He was a complete stranger. I didn't know him at all. He talked to me on myspace, and he asked for my e-mail. He knew I had a boyfriend he asked about my picture of him. Than he talked to me on my yahoo account from 12 to 1 in the morning. Whenever I wasn't there to answer him on my e-mail account he kept asking "where are you"? I knew he wanted more than the friendship with me. I wasn't interested in him at all, and I had the boyfriend I been dating for 4 years and I was in love with him. So I deleted him from my myspace friends and told him I didn't want to talk to him anymore and I wasn't interested in him and I had the boyfriend. He got offended. The week after he friended me again on myspace and I disapproved his friend request. And he left me alone since than. Why was he hitting on my like that when he knew I had a boyfriend anyway?
