In what ways does Tom remind Amanda of her husband?

Amanda is still fixating on the idea of the gentleman caller. She proposes a swap; Tom's freedom in exchange for a husband for Laura. Amanda is still putting her security into the hands of men. Indeed, perhaps she sees no alternative. Although her old husband's irresponsibility and Tom's increasing restlessness would seem to argue against the reliability of male providers, Amanda is still hoping to find an ideal husband for her daughter.
