"It's the little things we do without thinking that can reveal how we really feel, because we're not consciously controlling those actions."

From decoding the wav the two of you sit when you're out with pals to how your bed linens look postsex, our guide will clue you into the visual messages that can help you assess your couplehood.

* You Mirror Each Other's Movements

Zero in on the gestures you make when you and your guy are together. It may seem like coincidence, but if the second he crosses his legs or reaches upward to stretch, you do too, it means you're totally in s)mc. "Biologically, there's a tendency to imitate what we find attractive," says David B. Givens, PhD, director of the Center for Nonverbal Studies, in Spokane. "Mirroring occurs in most anima--and human--courtships. For example, when a male and female duck are together, they bob their heads and dip their bills in the water in synchrony." It's a way of showing that you're like-minded, which gives you the warm feeling of safety and security that's an important aspect of love.

* You Watch Each Other Walk Away

Yeah, yeah, we know--when you're first crushing on someone, you can't keep your eyes off each other. But when long-term couples still gaze at each other as they part ways, it shows they're beyond enamored because they don't take each other for granted, and they even feel a sexy sense of separation anxiety. "A lingering glance indicates that you want to relish and extend the connection," says Wood. "It's as if you're trying to take a mental snapshot of each other until the next time you see that person," You know you're probably going to cross paths again in a couple of hours or minutes, but you're still counting down seconds until you can be together.
