I believe that if the opposite end doesn't love you the way you
do, it will be painful. However, it will be heavenly if both sides
love each other very much regardless of what type of love is
it.
To have a choice to love is perhaps the greatest type of love for
it is plainly motivated by the objective itself rather than the
feeling itself.
Well, it is a rather broad area to touch on.So freaking difficult
to explain. =S
