Oh girl. Listen to me. You gotta stop emailing and calling him now and forever. He's given you a clear indication that he's not interested and you have to just let him go. Silence is an answer.

He used you but then, you seemed to enjoy it so just let it go as a sexual fling. Don't beat up on yourself for this, just learn from it. What lesson do you need to learn because of this should be your question.

Don't chase a man who is acting this way. It will only make it worse on you. Pick up your shoes and walk away with dignity.
