You Always Hurt the One You Love 
Mills Brothers (1944), Clarance "Frogman" Henry (#12 in 1961)

You always hurt the one you love
The one you shouldn't hurt at all
You always take the sweetest rose
And crush it till the petals fall

You always break the kindest heart
With a hasty word you can't recall
So if I broke your heart last night,
It's because I love you most of all
