Is he a real friend or not?

We recently became close friends but we've known each other for a while. We have great conversations and we enjoy each others company. We have mutual friends and he confides in me about things he wouldn't to his other friends. His behaviour could be deemed as flirting at times but I don't want to pay attention to it because with me once I call you a friend you're in the friendzone forever.

He likes playing with my hands, hair and weirdly my wrists as I speak. Sometimes he stares deeply at my face and says nothing. He always says I'm what he wants in a girlfriend but in a very subtle way ( he'll say "in a relationship I want someone I can learn something from and I'm always learning from you."). We were walking with our group one time and a friend of ours said they think there's something between us. I'm now analysing my friendship with him and I don't like that. Please help am I thinking about it too much or is there something there?
