I think it depends on the person, and depends on the couple. I found that the closer my M has come to the end, the more we were ML. Of course now that my H has checked into D laws and discovered he won't be able to file if we continue to ML I have been cut off .
We've gone long periods before, early in our R when he had to go home to England for months at a time because of his visa and other times when we both got busy and drifted apart. But now that things are really falling apart I think ML has been one of the few ways we've remained connected. So I'm upset that it appears we won't have that connection. It isn't about ML, it isn't about sex, it's about being close to someone you love.
