Obv don't know for sure but when I listen deeply to my lady, echo her feelings back to her so she knows I at least understand, then I hold her in a way that lets her know that I'm here and not going away, I find that helps a lot. Takes a lot of patience sometimes, I heard women have 40x hormones than men when menstruating, plus now a baby then postpartum on top. Yikes. I try not to take things personal. + She goes to therapy once in a while, nothing wrong with that.
Hope that helps, for what it's worth
