An abuser can seem emotionally needy. You can get caught in a trap of catering to him, trying to fill a bottomless pit. But he's not so much needy as entitled, so no matter how much you give him, it will never be enough. He will just keep coming up with more demands because he believes his needs are your responsibility, until you feel drained down to nothing.
