I agree with vinlad here. The thing with not returning calls is that childish little game, but also your calling him every day is more about control in his eyes. Break up your pattern of calls, including not calling him for awhile. He doesn't want to be controlled by "mom" which is you in his eyes right now. LEt him take or not take the lead on this one. Also, when he announces he has plans as he did, try not to ask too many questions, let it go and go about your business and you enjoy your night out later this week.
