Yes; I have experienced that.
My dad's brother died, he was only 22 yrs older than me, we were close,and it was a messy thing to reconcile/ go sort out his matters remotely offshore etc etc at the time. Which I did, readily. And I was strong throughout, I could just do that for ..someone I loved, the family; those who would, who could not travel so far.. The memorial service arranged by his friends, there (amazing!), the lot. Even at the UK funeral - felt v content, giving comfort to those friends who travelled so far. Quantum in me fuit.
...
and, then, about 7-8yrs later, over large dinner I'd prepared, at my house with extended family - some of the grief, and a lot of the good stuff.. just bubbled-up & -out. Found myself in tears of ..grief/ no perhaps , rejoicing: recollecting, recounting good stories, in a new light.
tl;dr:
It's different for all of us. Utmost sympathy for your loss; and - don't be surprised if the time you
register it, takes you by surprise. ATvB.
