Don't Wanna Fall in Love song meaning

The narrator of this song considers love a burden that makes you weak, dependent and is only made for people who are not self-sufficient and need to have a lover to feel secure. He prefers to be free and alone, because he doesn't believe in love and thinks that if he becomes a victim of this feeling, he will lose his independence and freedom. However, as harsh and cold as the narrator wants to seem, it's not the inability to love that makes him say "I don't wanna fall in love" - it's fear. He is afraid of love because he is afraid of having soft spots and opening up his heart. He'd rather sit there all his life alone, because this way he feels safer.
