How to Track and Use Glanville Dating History for Better Relationship Decisions

Dating history tracking is one of those things people either ignore completely or obsess over with spreadsheets. Most of the time it falls somewhere in between, which is exactly where it should be. The Glanville Dating History framework gives you a structured way to log what actually happened on dates, who you were actually compatible with, and what red flags showed up early enough to matter next time. Here is how to set it up properly.

Glanville Dating History

The Basic Setup

You need three data points per dating interaction: the logistics, the emotional read, and the behavioral flag. That is it. The logistics are straightforward. Date, duration, location type, cost, and who initiated. Nothing dramatic about this part. The emotional read is where people get it wrong. They write "we had fun" or "it was weird." Both are useless because they are impossible to reference later. Instead, write a single sentence about what you actually felt during the conversation. "I found myself checking my phone during the second course" tells you more than "it was boring." "I forgot what time it was" tells you something useful. The behavioral flag section is the core of the Glanville Dating History method. You log one specific behavior per date that indicates long-term compatibility or deal-breaker potential. Not personality judgments. Specific observable actions. Did they ask follow-up questions about things you mentioned? Did they check their phone during awkward silences? Did they remember a detail from earlier in the conversation and bring it up later?

The Template Structure

Each entry follows this format: Date and duration Location and cost

Who initiated One-sentence emotional read One behavioral flag

Follow-up likelihood (high medium low) I used to overcomplicate this. I added compatibility scores, mood ratings, and personality type guesses. That took twenty minutes per entry and I stopped using it after three months. The simple version takes about ninety seconds and I have been using it consistently for two years.

Common Pitfalls

The biggest mistake people make is retrospective rewriting. You go back to old entries and change them because you met someone new and your old crush looks different now. This destroys the entire dataset. The emotional read from that Tuesday in October was honest in October. It does not matter that you are now dating someone else and the old person seems worse by comparison. Leave it as written. Another issue is vague flag recording. Writing "they were nice" or "kinda rude" gives you nothing to analyze later. The behavioral flag must be specific enough that six months from now you can reread it and immediately understand what happened. I ran into a specific problem a while back where I was logging behavioral flags but not noting the context of the date itself. Someone who was quiet on a loud first-date bar might be perfectly engaging on a quiet coffee walk. Without the environmental context, my flags became unreliable. I started adding a one-line setting note to each entry. It fixed the noise in my data immediately.

How to Actually Use the Data

After about ten to fifteen logged dates, you start seeing patterns. Not in other people. In yourself. You notice which types of settings drain you. Which conversation topics make you lose track of time. Which behaviors in others consistently correlate with dates you want to continue and which ones reliably signal you should stop investing. The Glanville Dating History system is not about finding the perfect person. It is about reducing the number of dates where you waste three months on someone who was going to disappoint you regardless, because you missed the early signals.

Limitations You Should Know

This method has real bottlenecks. It only works if you actually log entries within twenty-four hours of the date. Memory decays fast. After a week, your emotional read is mostly whatever narrative you told your friends about it, which is already biased. It also does not help with casual dating where long-term compatibility is not the goal. If you are just seeing people without intention, the behavioral flag section becomes meaningless and you are better off just enjoying yourself. There is also a selection bias problem. You will naturally remember and log the dates that felt important. The forgettable ones slip through. Over time your dataset skews toward extremes, which can make your patterns look stronger than they actually are.

For people who want something more structured than a notebook, there are several apps designed for relationship tracking, though most of them are either too gamified or too clinical. The notebook or spreadsheet version of Glanville Dating History tends to work better precisely because it forces you to write your own descriptions rather than selecting from dropdown menus.

Getting Started

Open a notes app or a document. Create a new entry for your next date using the template above. Do not worry about making it perfect. The first five entries will feel awkward because you are not used to paying attention to your own reactions in real time. By entry number six or seven you will notice the shift. The process stops feeling like homework and starts feeling like awareness. The Glanville Dating History method is not a shortcut. It is a recording system. What you do with the recording is up to you. But most people, including myself, end up making better choices simply because they have actual evidence instead of vague memories to rely on.
