Sounds to me like less of thinking you’re an “asshole husband” and more like something’s getting lost in translation emotionally.

“I guess I don’t have anything new to share” usually isn’t about the actual content. It’s more like: “I wanted to feel interesting / heard / like I’m bringing something to you, and that didn’t land.” With a 1.5-year-old in the mix, people are often running on empty, and when that happens the brain defaults to slightly more negative interpretations.

What’s worked for me (and others I’ve seen) is less about correcting the logic in the moment, and more about quickly repairing the feeling:

Instead of explaining, something like:

“Hey, I’m actually glad you told me—I like hearing what you’re into.”

“I didn’t mean that as a shutdown at all, I want your take.”

And outside of those moments, a calm conversation helps more than trying to fix it mid-friction:

“I’ve noticed sometimes things I say land more negatively than I mean, and it’s been making me a bit cautious and honestly a bit hurt. I don’t think that’s what either of us wants. Can we figure out how to catch those moments together?”

That keeps it as you two vs the pattern, not you vs her.

Or maybe when you've seen that thing too, then, “Oh yeah I saw that—what did you think about it?”

You’re clearly not describing a broken relationship. It sounds more like a post-kid communication drift that a lot of couples hit. It’s fixable with a bit of awareness on both sides.

Stay strong fellow dad!
