He is your ex. In the past, he was jealous and possessive. He was very toxic in past relationships. He felt regret for what he had done. He only wants you to forgive him so that he can move on from you. He won't force you to love him again. He accepts your decision. But deep in his heart, he didn't dare to tell you how much he wanted you back. He really wants you to be happy with the one you love, but not him.
