Yes

This is what I think about the meaning of this song. It's about a couple who has recently broke up. The narrator was badly hurt because his girlfriend dumped him, he even believes she will never be able to help anyone in a relationship after hurting him the way she did. He wonders wheter she asks herself if he is feeling better now, maybe she even regrets her decision to dump him, she might have realised that she did it for no apparent reason and she wants him back. He answers her concerns by saying he does feel better and though he might not be completely over her, he feels well enough to tell her he doesn't need her anymore. He had a hard time after the breakup, but now he feels alright with the situation and therefore won't let her to come back to him and hurt him once again. This is confirmed towards the end of the song where he tells her "stay away I'm better". I think this is a great song and an underrated one, too. It's a little bit sad, but it portrays a real-life experience of getting over someone and not letting them crawl back because you need to move forward.
