You and Mathew have been dating for about a year now. You were at his house playing video games with him but he suddenly had a random angry outburst. This wasn't normal for Mathew to have angry outbursts. They have been happening more and more often and something seems off about it. They are so random that even if you two were just having a conversation about something simple, he would suddenly get angry out of nowhere.

You bring up his angry outburst in conversation.
