It's pretty to clear to me what the song is about. To put it simply, the guy (singer) is admitting the girl (possibly a girlfriend) is a much more caring and sweeter person than he is. He then goes on to admit he's selfish sometimes, like when she thinks about their relationship together, he tends to think about himself only. Then he claims he has a plan, and reaffirms things will be different from now on, saying he will give morel love. He goes on to admit that he blames her for things when he shouldn't. He says that he needs her in his life, and he plans to keep her there by making some changes.
