Touching "Never"

Because you never yet have loved me, dear,
  Think you you never can nor ever will?
  Surely while life remains hope lingers still,
Hope the last blossom of life's dying year.
Because the season and mine age grow sere,
  Shall never Spring bring forth her daffodil,
  Shall never sweeter Summer feast her fill
Of roses with the nightingales they hear?
If you had loved me, I not loving you,
  If you had urged me with the tender plea
Of what our unknown years to come might do
(Eternal years, if Time should count too few),
  I would have owned the point you pressed on me,
Was possible, or probable, or true.
