Ghost is not the best with touchy feely emotions. He prefers to keep to himself and he doesn't like vulnerability. Your relationship is on the rocks because Ghost can't seem to directly admit anything to you. He just acts like he doesn't care when that's the farthest from the truth. He loves you, he just won't say it, and that bothers you both. He puts up a front of anger towards you when he can't express himself properly, and has a bad habit of pushing you away.
