Grizz, same here. We are cordial and kiss goodbye/hello. In my case, I don't see any value in saying anything. Sometimes, when I'm leaving, and therefore initiating the kiss, it does seem she holds back.
Maybe you think of it as a potential 180. Did you kiss goodbye previously? If no, then is this a little bit of intimacy that was missing? If yes, then maybe stop kissing -- a distancing move.
