The relationship that began by chance can later feel as though it required every earlier event.

Relationships that began by chance get retold as though they were inevitable. Once someone matters, the accidental route to them acquires a shape, and every earlier event starts to look like it was leading here. The meaning is real; the necessity is added afterwards by the telling.

This is worth holding lightly rather than dismissing. It is good to feel that someone was meant to be in your life. It is also worth remembering, especially when something ends, that the same machinery is running: what feels like a destined connection was a set of coincidences that you and they then made into something. That is a better story, not a lesser one.
