He is HARDENEd. His heart is hard! He knows you are good but he also has insisted into himself and he knows he is a hard, cold man. He will not let you go completely and he feels that there is a connection and you belong to him but he wants also to play around and deep in his heart, he knows you deserve better. I also sense your son is not his and he does not feel he should have to take care of another man’s child.
