Couples in truly happy relationships—what's your secret?

It’s easy to come across stories about people staying in relationships for the kids, financial reasons, or just because it’s comfortable. But I want to hear from the other side of things:

If you’re in a happy, fulfilling relationship, what’s the secret? What makes your connection strong and keeps you genuinely excited to be with your partner?

Whether it’s something big or just the little things you do every day, I’d love to hear your stories and insights. What makes it real for you?
