Teresa Ibarra used Facebook Messenger to text with her now ex-boyfriend almost a decade ago. She exported the messages and analyzed keywords and topics used over the one-year relationship.
I can’t say I recommend it — it was surreal and uncomfortable to read through messages from a decade ago. Programmatic analysis can reveal things about yourself, your partner, and your relationship that you may not want to know or accept.

You automatically get context for every data point because you lived it, so it’s easy to see how data doesn’t always match what happened in real life.
