First off...the Adele song is about being LEFT by her boyfriend...she was famously dumped by him and wrote the whole album as a sort of cathartic thing...a "been done wrong by" album and now that she is in a healthy good relationship she has said that she hopes her music is still popular
I think it is about guilt...guilt about leaving, guilt about leaving the way they left, guilt about still feeling love but nothte kind of love they are "supposed" to feel, guilt about not being able to explain that to the person they are with now...
you know, we all have this vision of how our lives will be when we reach a certain age or stage of our lives
and
when our lives don't follow that vision, we get disappointed and need someone to blame (well most of us ) so we think if we get rid of this person we are blaming maybe then our vision will get back into focus...
but it doesn't
but we still can't see the that flaw is in our vision
it has to be somewhere else
so we might even start blaming ourselves
along with all of those things comes guilt
we might even change the vision to be a new vision but there is always THE vision
we have got to let go of THE vision
because there isn't one
there just IS
if you are always comparing to a fantasy, you will never be happy
) so we think if we get rid of this person we are blaming maybe then our vision will get back into focus...
