Caught My Wife's Eye at Chez Usual Friday Night Routine

So, last week I decided to take my wife out for our usual date night spot, the fancy steakhouse in town. We've been married five years now and have visited this place almost every month since we started dating. But there was something different about tonight. As soon as she took off her coat and let me see what she had on, I felt a spark in my chest that made my heart skip a beat, she looked incredible. Now, I've always been one to pay attention to the little things my wife does for us each week: a new perfume here, some sexy lingerie there. But tonight was different, it wasn't something obvious like her cleavage or legs; rather, it was this subtle play of light on her face as we walked into the restaurant and her quick smile when our server took note of her beauty too. We started with appetizers, which went smoothly enough until dessert came around. You know that moment? It’s when you're sharing a chocolate fondue and feel like time just stops for a second while your eyes are locked onto hers through the little bubbles in the dip? Yeah, I felt that tonight, and it wasn't because of the chocolate or even the wine we'd been drinking. That's when things got interesting. We were finishing up dessert and I noticed her leg brushing against mine under the table, a gentle caress that seemed deliberate despite being almost unnoticeable to anyone else around us. It was as if she wanted me to know, wanted to share this moment just between the two of us. And here's where it gets tricky: when we got home, I made sure to be more affectionate and loving than usual, but I couldn't help feeling conflicted inside too, wondering about what that look meant from her tonight. So now, here’s my question to you all: Am I being a paranoid husband or did something genuinely change between us during dinner? And how should I approach this delicate situation with my wife tomorrow morning? It's driving me crazy and any advice would be hugely appreciated.
