Could he possibly feel the same way?

I met a man in 2017 who I was immediately attracted to like crazy. I often think of him to this day and decided to see him at his work randomly because I was in his city. He actually remembered me. He remembered! I was shocked happily. However he starred at the wall the entire time and when I told him it was nice seeing him again he said nice Seeing you too in a weird slow way. Should I send an email?
