"After many years, if I don't marry, if you don't marry" is the sentence in which poem?

Jimmy said, when you like me,

I don't like you. I like you when you love me.

I fell in love with you when you left me.

Are you walking too fast, or am I unable to keep up with you?

We missed Noah's Ark, we missed Titanic,

Missed all the thrilling and not thrilling, we still have to

However, please allow me to say such selfish things.

A few years later,

If you're not married,

I'm not married,

Well,

Can we be together?
