LF Post war, 8th year with trauma and angst

I can’t remember the title! Please help.

It is mostly HP epilogue canon compliant, except Hermione and Draco have an affair when they return to Hogwarts after the war. They are broken and drawn to each other, but they are also juggling their other relationships- Draco and Astoria, Hermione and Ron. They eventually go their separate ways. It ends where they reunite at platform 9 3/4 after dropping off their kids; Draco is widowed, Hermione is divorced.
