I really loved this. Beautiful angst, but without being over-the-top and hard-hitting angst; as great as that can be, I agree with psychme that these two are more about the small frequent hits than clobbering ones. And you did this so beautifully - I especially loved how you showed us the scenes out of order; it emphasised the decline of the relationship.

Also loved the (incredibly sad) comparison to the Schuesters at the beginning. Very possible that Rach could end up like Will if her Broadway dreams were somehow dampened. And I love your take on Puck's grown up career; from pool boy to plumber, lol!

The ending was perfect, just the right amount of hope without the promise of a happy ending. I love realism in fics, and yours are always great.
