Help please

So here is the full story.... so my friend had been dating a guy for two years. They decided to spend the day with me and he brought us food. However, they just got into a big argument at my house because he seemed to have gotten the wrong order for her. At first he started saying he didn’t see what she wanted on the menu and therefore what she wanted couldn’t have existed 🤷🏾‍♀️He then started having an anxiety attack because he could tell she was unhappy. She told him he could’ve done more to make sure she got what she wanted along with other passive aggressive comments. He starts yelling and screaming and literally throws himself down on the ground because he claims she’s not listening and doesn’t believe he tried his hardest to get her order right. She just told him to leave the house.... I’m trying to comfort her but idk what to say. Does this warrant a break up?
