Creepy Conversation

Last year during my visit in New York I had a rather creepy conversation with The Guy. My problem is that I love him but I didn't fess up yet. One evening after he had a stressful day he wanted to go for a walk in the night. We were walking next to each other for about one hour. Neither one spoke a word. When we arrived in his street again I thought "Oh man, I love you so much." I swear, I didn't say it, I was just thinking it. And I didn't say it silently, it was really just a thought.

Right after that he said, "I know." Loud and clear. It's been one year ago, but I'm thinking about that moment so often. We didn't speak for about an hour and then he suddenly says "I know" as an immediate response to my thought. Did he "hear" my thought?

And what the hell does "I know" mean? It's obviously not a "I love you too". But it isn't a "I don't love you" either. And what would he have responded if I said it out loud? Was this answer even intended for me? Was it coincidence? If I only knew ...
