I think you can use your imagination. But in something related, many many years ago, there were two men who were chavrusas, who learned at home, and the wife was always around and in the end she divorced her husband, the chavrusa divorced his wife and they married each other. If your imagination doesn’t suggest anything, would you want your wife to get too familiar with your friend?
And I’m aware of a similar situation with a brother and sister in law, married to siblings who then divorced and married each other. Do we ban family getting together as well (just noting the logical inconsistency, not arguing for either side).
Perhaps that was th RBSO’s plan to get the Bashert’s together?
