End a Fight. Stat.
So your guy said something hurtful during an argument. It sucks, but instead of lashing out, keep in mind this finding from Baylor University: when couples fight, they pick up on anger and overlook sadness, which escalates things. So ignore his pissy-ness, and address why he’s most likely upset. For example, if he says something mean about your skipping his work event, respond as though he said what he’s really feeling—that he’s bummed you didn’t make him a priority.
Aw, poor guy just needs a bear hug
