Switchblade lyrics

what I saw in you breaks my heart in two cause now I know you did not want to but mum did quite a lot to help you what I got from it is that I'm nuts incapable of relations can't talk to anyone what I saw in you breaks my heart in two cause now I know that I loved you but I had to learn to live without you I had to learn to hate I had to learn to hate what I love how could I know that it's so hard to switch hate off
