Cover art for Promises lyrics by Badly Drawn Boy

The song is about a man who marries a woman and talks about how their fire burns so slowly at the beginning but then it burns strong. They're making promises to each other, vows, and creating the strong bonds of marriage that SHOULD last forever.

However, the woman breaks the bonds of marriage and then their fire doesn't burn strong anymore. Think of the lyric, "It's the laugh of the last dying ember." and also, "A promise SHOULD last forever."

"Do you want to walk alone? How long can we carry on?" are other lyrics. My guess is drugs or something and he didn't want to put up with it anymore. So, he had to be the bigger man and leave her to whatever it is she may be doing. Their love is no longer strong.

"Sometimes you just have to walk away..."

That is what this song means to me. You may not agree but I've thought long and hard about it and this is what I've gathered from the lyrics and tone of song. The genre and speed gives a lot away.
