His story is not only his present living environment, but also his past life experience. Perhaps, he once met a non-human, and talked about love several times, but all ended in vain. He did regret it once, but now that he has met you, he feels that all this is lucky and the best arrangement. Perhaps, his career is not smooth, and his job search career has hit a wall everywhere. He is willing to work hard, but he can't guarantee you a happy future. He told the truth of everything. He knows you may leave him, but he thinks you have the right to know. Love makes you a whole. You should not only "share happiness" but also "share difficulties". Such a man loves you and doesn't want to hide anything from you even though he knows he may lose you.
