Ok, I think you should take some time for yourself to do something enjoyable. You don’t need to talk to him right away. But, you don’t want to give him the silent treatment like he did you: unexpected and rude. Since he is calling you, I say text him and say you’ll talk to him at a set time later: “Hey, I’m pretty upset that you hung up on me. I want to take a little time to cool down. I’ll see you Thursday at Taylor’s.” Or “Let’s have dinner Thursday night” if there aren’t already plans. That way he knows it will end, and that he just needs to give you a little time to get over it. And if you don’t get over it? Well, that’s your answer.
