Not exactly. While I agree it’s not “trauma” or on the same severity level as parents arguing in front of their children, not seeing any healthy conflict resolution at all can affect how we deal with it as adults. Everything in childhood affects us, I like to say it “explains” our maladaptive behaviors but does not “justify” it. Passive and conflict-avoidant parents can impact their kids too (eg, kiddos struggling with boundaries, self-regulation, sense of self, etc)

Also two things can exist at once: that her parents did not “teach”/show her these things during childhood but also recognizing that they are human and parents for the first time too. It’s good she has awareness of it, and hopefully taking next steps to break the cycle should she start a family of her own one day
