When he says "I will be waiting here, only to roam" I think he means he's trying to find someone else, and get over his pain. This is because when he says "Never going to belong to another" he's saying something happened between the lines of break up and this girl's death. So when he says "Leave me alone, I'm not an angel yet" it hints that he must've done something wrong to harm this girl to make her break up, or (worst case scenario) die.
When he says "My candle shines without a doubt" he's saying that he still loves her. And when he says "But the wind in your wings blows them out" he's saying that the fact that she's dead makes him sad. "And your wings are gonna have to wait" means that she's supposedly in heaven, but he's telling her to wait for him there.
