I was wondering if you thought it could be stbxw's point of view
I don't think so, W hasn't truly sobered up from the intoxication of her sins yet. But it could become her viewpoint... some day.
I have heard lots of interpretations over the years for this one song. Whether it's about an unwanted pregnancy or STD's or whatever. Personally, I have always considered it to be much simpler/subtle than that -- that it refers to the natural attraction men and women find in each other and how so easily the "in love" feeling can lead us into actions that alter the paths of our lives forever, for both good and bad. I really think it speaks to the dangers of what I now know is called "limmerance", the intoxication of the "in love" feeling. In other words, Lust.
So, yes, it can be applied to these WAS's who commit adultery, whether they care to recognize it or not. But it applies equally to any of us with or without other commitments.
This song has an added, very poignant significance to me in addition. I distinctly remember that song playing on my car's stereo on the second date with W, so many moons ago now. We had just completed a very nice dinner and we had parked in a quiet, secluded parking lot of a baseball stadium, to talk and continue to get to know each other better. When this song came on, I paused in mid sentence saying something to W... I had always loved the song, and it was part of a cassette tape mix I had recorded -- when it came on I couldn't help myself but notice. I pointed it out to W, asking her to listen for a moment (I love Dave Gilmour's work.) And then we continued onward in our convo, obliviously. I was already ensnared by the heady feelings the song speaks of. It was too late for me at that point, and yet the song continues to haunt me, especially now.
I wonder if it was truly a warning I failed to heed.
