Colleagues having affair

[hedgehogsinthehedgerow]

I know it's none of my business but one of my colleagues (20s) told me she's been having an affair with the boss (50s) for years. He's married with kids and had seemed really nice. She's getting favourable treatment. My other colleagues have no idea.
I'm self-employed so have no employment rights or HR or anything. Very few other jobs right now so it's not like I can move. It just feels really difficult as a situation to be in and upsetting to think of his poor family. It could harm my career as he's been frosty with me since she told me. It's made my workplace awkward and I really wish I didn't know. Anyone else been in this type of situation? TIA

Maybe I had been overthinking it e.g. what to say to colleagues if/when it blew up.

Just a suggestion, but how about… nothing?

You’re overdramatising the situation. You’ve heard a bit of gossip at work; you’re not being asked to break the Official Secrets Act.

Apart from this being a really great way to put yourself out of a job, who even has contact details for their boss’s wife? I don’t even know my boss’s wife‘s first name!

Very difficult situation. From a moral standpoint, I’d want to tell the wife. From a self interested standpoint I’d worry that if it got out from another source the boss would assume it was you that spilled the beans, which could potentially complicate things for you a lot as a self employed person.

If the latter concerns you then maybe it’s worth having a talk with him to say you’d really prefer that she hadn’t told you, as it’s put you in a really uncomfortable position, but that you aren’t going to tell anyone and perhaps he needs to have a word with her, because at the very least her telling you has objectively made your time at work much more awkward and uncomfortable.

Thanks Imbrocator that's good advice. It might be hard to get in a situation where I could have that kind of a conversation with him, and it's quite personal so could be awkward, but agree it would be a good idea if I can do that. It's definitely a concern that if it gets out now I could be suspected even though I won't be telling anyone.
