As for the Delacour family, Fleur and Bill eventually became soulbonded. With the concept of soulmates gone, the Veela have learned to not dwell on it which had caused their own pain and suffering and instead looked towards the relationships they have now. Some did split, but Fleur and Bill ended up forming that bond. Eventually after a few decades, she became Matriarch and left her own mark on the world. She passed away not too long before Daphne and I did.
