Hi there - it may be this "My gut instinct is that it's a gesture to get your attention"
but on the other hand it could be a freeing up of inhibitions that can build up within a M when partners have got a point where they're not communicating freely with each other...
I for one know now that there are things I could say to my W (from whom I'm separated) that I wouldn;t have dreamt saying before - that was the problem really when it comes down to it for me - "communication". Perhaps the non-verbal behaviour you've witnessed is a manifestation of something along those lines?
