Didn’t you guys ever have chosson classes? My mashgiach who was a talmid of R’ Shlomo Wolbe told us in the first chosson class that this mishna is not applicable to todays generation. Additionally, ‘Sicha’ depicts wasteful, ‘shooting the breeze’ conversation. When dealing with you’re wife, there is no such a thing as a waste of time; she needs the emotional connection to you, and if you think you or her are ‘bigger than that’ You should put some more time into your relationship, BECAUSE IN HOW MANY OF YOUR OTHER RELATIONSHIPS DO YOU COUNT YOUR WORDS!
