Mother.

She says she doesn't care about him.
She says she's better off without him.
She says she wished she married someone esle.
She says to pick someone wealthy.
She says to pick someone smart.

Doesn't she know that wealth is not forever?
Doesn't she know that someone smart doesn't mean he'll love you?
Doesn't she remember the reason she picked him?
Doesn't she remember the happier times?

She is the one who is so worried about him not calling home to say he's safe.
