My boss was our (wife and I) friend since middle school. He fancied her at one time, lucky for me we got together first. The last 3 years was tough for him with a flagging marriage and business impacted by covid restrictions. He pulled me in to help with the business. We managed to keep the business afloat but he couldn't save his marriage. Recently we've started to invite him for dinner several times a week after work. He always thought of my wife as a model wife and I suspect he still fancied her. Hence my dilemma, I can egg them on subtly, talk to her openly about being a hotwife with the boss or stay silent and nothing will happen.
