Please help me, why is he doing this?

[SN]

This guy has hurt my feelings many times, has broken up with me many times, once i cried in front of him because of this and he was still being mean telling me to go away and never see him again.After that he apologized but was telling me hes looking for a casual relationship, he has been saying that he doesn't want commitment from me since a long time.since an year hes been saying this.
Now recently two weeks ago he called to apologize for the way he behaved, but then again the next day he dint call me and dint contact me for 3 weeks.
Today he calls me, I dint pick up the phone and he called me thrice. I don't know why is he calling.
He knows that I love him but he doesn't and he has told me that he never loved me. So why is he calling.
I hav no interest in being with him or any otherguy anymore.
I would appreciate the opinion of a young guy.
