A piano-heavy ballad, "Lost On You" finds Lewis Capaldi accepting that he's not able to carry on with his lover. He tells her despite their best efforts, the relationship is bleeding him dry. You know that I adore you
Though I couldn't give enough
Hope you'll be safe in the arms of another
'Cause I can't take the weight of your love
It is likely Capaldi is referencing the same split with a long-term girlfriend that he sings about on "Bruises
." That breakup was amicable.
