I did a typo, I think.

I never dared (?) we [NOT you] couldn't survive, i.e. "we" as a couple, I think.

Don't forget that some rock lyrics are not great literature. I saw a documentary on Metallica and sometimes the band members just cobble lines of lyrics together into a semblance of making sense, and it appears that what matters more is whether the words fit the melody. It explains why some of their songs are a bit obscure when trying to work out the meaning. Maybe there is no meaning, or maybe just a thin layer of intention rather than fully explainable meaning.
