Hunt him down and ask him to his face if you can't call him. If he is that important, then go find out what is going on.
It began yesterday when you didn't do what you said you were going to do, nor let him know. You should have found a way. Because you didn't he is hurt and upset. So if he is that important, you need to go tell him you are sorry and you made a mistake. At the same time he over-reacted too if that is the ONLY reason he did what he did. Hopefully an apology from you will get an explanation from him and the two of you can work this out.

tbh i think thats alittle clingy of him if he got pissed at u for bailing on him once. if he means a lot to u try to get him back if u really think it won't work move on its better then sticking around..
