Or maybe he is just a jerk who was too "busy" to contact you and figured he would send you some bullshit message acting all concerned at the last minute on Friday night, pretending that he thought YOU were supposed to contact HIM. Until you know him better, don't give him the benefit of the doubt. 99.9% of men know how the "game" works...even in this day and age, we wait, and they do the calling. I don't mean women can't take the initiative every once in a while, or call more once the relationship is established...but, we all know that calling them too much in the beginning is a no-no. He should have called or texted YOU to check on the weekend plans, and waaay before 7pm on Friday night.
My advice would be to continue with the plans that you made with your friends, while sweetly telling this guy that when you did not hear from him, you thought maybe something came up and he was busy. If he likes you, that will be no big deal and it will also be a little lesson for him to make sure he keeps in touch about plans. If he has an issue with it, and thinks you should sit back and make no plans just in case you hear from him...well, there are plenty of fish in the sea. There is one thing that is definitely true: men who are really interested in seeing you will pick up the phone and call.
