C_A, this was absolutely wonderful! So bittersweet, so hauntingly beautiful.
And this was so achingly resonant:
Strength, even the strength of a superhero, ran out. Someday he might find himself in her doorway again, because he might realize that he could not stay away when she called for him. That being with her, even if only for a little while, hurt less than being without her for the rest of his life.
That's ... yeah. I have no words. It's perfect. Heart-shatteringly perfect.
Thanks for sharing this on the boards, C_A!
