We'll share a shelter, have mice in the bed

The story:

My boyfriend had made me a mix CD including this song and I always thought this part of the song was so romantic in an odd way ... as if he meant to say, even though we are poor, we'll still be sharing the same roof together. Then one day I realized that we're not poor and that having mice in the bed is not romantic at all, so I finally looked up the real lyrics at the public library...
