I believe this song is about a rebound. He is in need of being with someone right now - which is common after a break up - but is not ready to give love yet. Therefore, he doesn't want to receive love. He just wants things to be uncomplicated, he doesn't want this new person to fall in love with him, just take care of him. The "give me something to eat for I'm weak to my bones" could mean that he wants this person to nurture him with love and care, because he is empty from his previous, broken relationship. "Give me glimmers of hope" means that he wants to feel something, just a little bit.
And he knows he will leave, and he feels awful about having strung this person along, while he cannot give that love back.
