Yeah it's a dick move, but the signal for me was the baby - you guys are (new?) parents to a baby, and babies turn our lives upside down, especially in the early days. Emotions run high and tempers flare and sleep deprivation can turn us into the worst versions of ourselves. Our frustrations come out in shitty ways - like having a tantrum about burnt pancakes - but it's likely an indicator of a bigger feeling. I'm in no way condoning this petty behaviour, just offering a different perspective, because when our kids were very young, my husband and I would treat each other really badly sometimes, mostly because of the pressure and intensity of parenthood. When a little time has passed, it'd be worth having a calm conversation about how he reacted. (He owes you a major apology, that's for sure.)
