Analysis of A Question

Love, wilt thou love me still when wintry streak
Steals on the tresses of autumnal brow;
When the pale rose hath perished in my cheek,
And those are wrinkles that are dimples now?
Wilt thou, when this fond arm that here I twine
Round thy dear neck to help thee in thy need,
Droops faint and feeble, and hath need of thine,
Be then my prop, and not a broken reed?
When thou canst only glean along the Past,
And garner in thy heart what Time doth leave,
O, wilt thou then to me, love, cling as fast
As nest of April to December eave;
And, while my beauty dwindles and decays,
Still warm thee by the embers of my gaze?
