If you are the only one calling back up - its difficult for men to express their feelings. Never ask a guy where do you see us/this relationship heading? Just go with the flow and enjoy the now. Enjoy the moment, live in the now - especially if it is early in relationship first 6 months. An indication of how in to you he is will be if he is ringing you more than once per week to arrange catch up. If he is calling you to say hi, hear your voice, see how your day was. If you are doing all the chasing back up and let him.
