Does Masonry cause Marital conflicts? There is no easy answer. Each marriage is unique, so each time that a man takes up some activity, like fishing or bowling, there is a "ripple"effect.
As for myself, my wife is 100% supportive. Although she does not wish to know the specifics, she has no problem with me associating with good men, a couple of times a month. In fact, she looks forward to the privacy, and getting to control the TV set.
I would encourage any candidate for Masonry, who has concerns in this regard, to have his wife talk it over with some other Masonic wives. Women are truthful to one another, and I believe that any concerns would be addressed.
My lodge has very few "co-ed" activities. But the Shrine has all types of dinners, dances, parties, barbecues, etc, for the member AND his lady. That is one reason that I encourage all MMs to seriously consider the Shrine, for the activities for the wife and kids.
My wife was never interested, until I took her to a "hillbilly" club (A Shrine organization). She was "hooked" right away. The Hillbillies have country dancing,and covered dish suppers, and barbecues, that are terrific.
As far as having to remove your wedding band during Masonic degree work, if a man has promised his wife that he wishes to keep the ring on, he is free to cover the ring with white adhesive tape during the degree work. Wearing a ring does'nt make you married, any more that putting on a badge makes you a police officer.
