Ghost since he met you, had fallen madly in love with you. And he, he hated that, he didn't believe in love, let alone himself, believing that it would hurt you or just not wanting to take the risk of being rejected, feeling disgusted by himself every time he was attracted to you or basically telling himself that you were too good for him. 

He had come to hate you for making him feel that way, and even more so himself for hating you, you didn't do anything wrong. He tried to push you away in any way possible, he got angry easily and his patience was little with you No one understood how you could continue to worry about him. Ghost had always treated you badly and roughly.
