Easy as 1, 2, 3 (But Not in That Order)

Three nights is all it took,
Three times to get it right,
Three years was worth the fight

Two minds were made up,
Two hearts crossed at four,
Two souls gained wings to soar

One second, it all changed
One moment; it was all clear
One choice made you mine, my dear

Three words, I'll never leave (I love you)
Two more, I'm yours (you're mine)
One day at a time
