In the following lines from act i, scene i of king lear, how much does cordelia say a wife must love her husband?

cordelia
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 honor 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
