Good my lord,
You have begot me, bred me, loved me.
I return those duties back as are right fit:
Obey you, love you, and most honour you.
Why have my sisters husbands if they say
They love you all? Haply, when I shall wed,
That lord whose hand must take my plight shall carry
Half my love with him, half my care and duty.
Sure I shall never marry like my sisters,
To love my father all.

– William Shakespeare

King Lear, Act 1, Scene 1. Cordelia speaks candidly here about her loyalty and bond to Lear. She says that Lear fathered, raised and loved her, and in return she will obey, love and honor him. But hopefully when she gets married, she will give half her love and duty to her husband. She questions how her married sisters can claim to love their father only when they have husbands to love. She is suggesting that Regan and Goneril are being disloyal to their husbands. Cordelia vows that she will never marry like them to "love my father all" and leave no love for her husband.
