What's going on, guys (and girls)?

I went on a date the other day with a girl whom I met from Hinge. She messaged me first and we arranged to meet on our day off. She travelled down to me by train.

I already knew that she would reject me and wouldn't be attracted going into the date so I didn't really look at her or smile when we met but I did buy her a coffee and we went on a walk. We spoke for a bit about life and what we get into in our free time. I had to leave after about two hours as I was getting hungry so I walked her back to the station and I told her to message me when she got back safely. I never heard back from her.

What could I do differently in future? This wasn't the best date.
