This is for the guy himself, the one who had the affair. Hi. What an awful situation - uncomfortable doesn't really begin to describe it. However what's done is done, and if you are now with the wife of the boss, then clearly you and she are happier in that state. Even if not, clearly life is once again far more complicated than we ever envisage, and you have both chosen the difficult path. So what to do? Let's paint three options - fight, flee or transition. Under Fight, you would stand your ground, and insist that business is business, and personal matters are separate. With Flee, you'd exit immediately and allow you and your new partner to start a new life together away from her former husband. With Transition you'll take into account the knowledge that things will never be the same at work, and negotiate a graceful exit and transition, perhaps retaining a share of the business, and also ensuring that you formally settle any claim on the business the wife may have. The Fight approach may seem logical, in a Spock kind of way, but it is bereft of all feeling. You will be demonstrating to all around you that you are completely non-empathic, and some may start pondering your scores from The Psychopath Test (book). I suspect that it would result in an uncomfortable work and personal experiences which will almost certainly end badly for all parties, including the business and the ex-wife. The Flee approach is the most empathetic, signaling that relationships and family matter more than business, which is a view held by almost everybody else in the world. It's kindest to your Boss, and to your new lover, and allows you all to make genuine re-starts. However you'll lose some of the benefits from being in the company, and you will leave an immediate gap with your knowledge and skills. The Transition or negotiate and leave approach is probably wisest. The transition period could be days to months, but does need to be defined and progress monitored. You would each agree a list of tasks to complete, and on a way of behaving to each other. You may (should really) choose to have a third party or two involved with this negotiation, but don't hire expensive lawyers and do it in court, for obvious reasons. Come to a rapid agreement within a few days, and then honourably complete the terms. No doubt there are other approaches, and they should be considered as well. All of them should include a genuine apology - indeed a series of genuine apologies. Of course it wasn't entirely clear whether you are still with the ex-wife, but even if it was a fairly brief fling, serious consideration of the approach to take and the apologies is still very valid.
