It's too complicated.

Too dangerous to

Fly

because the risk of falling is much too great.

It's much too wonderfully painful

They're too easily addicted to passion,

Though, soon it begins to fade.

He ignores it and she denies it, but reality

Overcomes them.

She gives him her strongest look of pleading,

But like he says, this has to end eventually…

And he's afraid of getting too attached again.

They might as well not love

(fly)

At all.
