This is fascinating. Looking back on my ~4 year relationship with my soon-to-be-wife, I notice a lot of parallels. Looking back even at our last week of texts, it's all transactional and logistical things: pickup times and places, confirmations, and quick tasks.

It's not necessarily that our communication has lost that "fresh love" spark, merely that it's developed and aged (like a good cheese) into deeper, more meaningful transactions that happen in person. We no longer need to reaffirm anything over texts, because everything meaningful happens in person.
