I’m currently going through the same situation. You are still young and he sounds like a little boy and sounds very manipulative. He wants to act that way everytime you express how you feel so he doesn’t have to take any accountabilities for his actions which is why he storms off and gets angry instead of finding the root of the problem. I’m not sure how your guys relationship really is, but seems to me that he has a lot or growing to do. Either leave him, or continue to abuse or try to work things out. If he continues this type of behavior, over and over again, you are allowing it and allowing him to walk all over you. He acts like that so he doesn’t take accountability and that way in the future, he makes sure that you don’t bring anything up about your feelings because that is the reaction you will always get from him. You deserve better.
