ring to find a specific poem in which the sentiment is that life happened while thee writer was busy loving someone, how they could have done loads of stuff but they were just getting on with loving their partner. My Google skills have let me down. Not helped by the fact I can't remember where I read it who it was by or any of the words! Suggestions please!
John Lennon said that life is what happens when you are busy making other plans, but I don't think that's what you are talking about.
Your mention of the poem is vaguely familiar to me. I have a small memory of something like that. Maybe it will grow overnight.
Sorry not to be more helpful
