I think it's pretty obvious what this is about, but I'll say what I think anyway.
Obviously it's unrequited love, she wants to see him, to be with him - but at the same time it hurts too much knowing he'll never feel the same way about her. That's why it hurts to look in his eyes, to see him with someone else. She wants to see him, because she loves him, and seeing him is a high, but she also knows how quickly he can (and will) take that high away from her, when he makes her realise that he'll never feel the same way. And she just wants to be comforted.
It's a song that we can all relate to. Which I think most of La Roux's songs are.
