First
We were so young when we met, just sixteen
Didn't know where I was going from there
Butterflies, shakes, first kisses, and dances
Reminders of those early days with him
Time went by, my heart grew fond, I felt trapped
Because he threw a curveball to my life
His attitude changed, I felt sad, confused
One summer we went away and love won
Every piece of suffering is old now
This love is real, eternal, and all mine
"Because he threw a curveball to my life"
That line's in perfect blank verse form. Good job!
I like the punch these simple words convey.
