Why did he hug me for so long?

I was out with my friends at a bar when all of a sudden I see the guy I used to have a little thing with and was a good friend. We hadn’t been in contact for about two months, and when he saw me he walked straight up to me and wrapped his arms around me. He held me for about ten second while squeezing gently. When we pulled apart, he held my hand and was rubbing my hand with his fingers while holding it, and he introduced me to his best friend (who based on his reaction to hearing my name knew who I was), are his feelings still there?
