He always said they'd always have each other.
He always said that they'd never be separated

She feared the day he'd leave her.
She feared he'd forget her.

He did leave, but they stayed together and he started saying things.
He told her that he wants to wake up and see her face in the morning.
He told her he wants to be able to have her arms wrapped around him all the time.

He wanted to marry her.

She wanted the same.

So when that day finally came, and he watched his bride walk down the isle, she sat there thinking, she's beautiful, as she watched the love of her life get married to someone else.
