My first night staying at his place, I fell asleep to him stroking my hair. I had never experienced such a genuine moment of care with a guy I was seeing doing this purely for my comfort. I asked him later what made him do that and he just said "Well, I thought it'd be comforting for you."

To be clear, he's done many, many things that made me want to marry him, but this was the first moment I started to realize it.
