Lyric discussion by chewedbluecrayon 

To me it sounds to me like her relationship with this woman, be it a friend, mother or her lover is abusive. But she accepts it because there's this rhetoric about doing this because I love you, I'm protecting you. "she loves me more that anyone who wouldn't raise a hand" (in anger).

This woman is so afraid of men, the world that she's stifling the writer, "she keeps mace spray for you can't rely on the common man"

I agree with monster that the second verse is about an epiphany, but this woman is once again trying to stifle it by telling her it wont amount to anything. "But she would say I won't find my way through the plaster; I'm an empty hourglass in the sand"

But once again the writer is so under the thumb that these words aren't seen as coming from manipulation but love.

the second stanza to me is about an attempt to escape from the control through sex, she has to 'let it all go'. but then she can find the strength or she's afraid so she convinces herself 'she loves me'.
