Anybody know what this is?

i met this really great guy a while back and i feel like we really connected...to the point where i'm thinking of him and my phone will ring and it will be him! or just randomly during my day i'll think of him and then find a text or email or something from him. we really seem to understand each other and can read each other quite well. we're not really dating or anything yet, but he's one of my best friends and i'm not quite sure what this intuitive feeling i have about him is. any ideas?
