I just don't really believe him about his mother. I think he's lying to you. If he isn't, there'd have to be really strange circumstances like this was his first opportunity in a long while to see his mother and he had no choice but to give it such priority that he had to break a date with you. I suspect he simply had something else that he would rather be doing and broke the date because he wasn't that into you. I'm sorry to put it bluntly. It's just my gut feeling.
