Marriage isn't destroyed by one dramatic moment. It's weakened quietly, in the small things we stop doing without noticing. And a wife who no longer feels safe, seen, or desired slowly becomes a version of herself that feels far away.This book is for the man who's done with that distance.Be Her Serotonin focuses on tiny, practical habits that shift the emotional temperature of your relationship in real ways. No clichés. No perfect husband nonsense. Just clear, simple actions that make your wife relax around you, trust you again, and feel genuinely cherished.Some habits take seconds. Some require intention. All of them change how she experiences you - not as someone she has to protect herself from, but as the man she can lean into emotionally.If you want a marriage that feels warm, steady, intimate, and alive again, this book will show you how to build it through consistency, empathy, and the kind of everyday effort that makes a woman think, I'm safe here. I'm loved here.Not with grand gestures.But with the small things that matter every day.
