im an aqua and if im not calling the girl is because i dont miss her, and dont worry, he will call if he misses you. keep calling until you get the sign that he's not interested. You were the last person to call? he knows is his turn, he is not playin hard to get. The only reason he is not is because he is not really into you. If you really like him, tell him straight up, but dont ask him how he feels. he probably wont tell you the truth not to hurt you.
ps. we get attached really easy. if he liked your company he will make the first move to hang out.
