i wonder...

once the dynamics of a relationship/friendship change, is there any hope to ever having it return to the way you'd once known it? if something changes, and you are left with something that barely resembles what you were used to.. is it at all possible to go back to normal? do you just move past it and hope that you can build it back up to what you'd known and loved? or do you just give up and accept what has happened as fate and something that you cannot control or change?
