So, I had a high profile/high pressure job with some of my H's colleagues. I was working away from home as well for this, and staying in an apartment.
I was absolutely exhausted from it, because as well as the job, colleagues were (mostly) saying how sorry they were. I kept my answer very, very positive, thanking them for their concern but saying (and also behaving) like I was doing really well. It wasn't an act, as that wouldn't be right, but a slightly amped up version of the truth, if you like.
Those colleagues were all shocked at how much weight I'd lost (it was the first time I'd seen them since this all happened).
There was one who asked a little more in depth about me, and if I was OK, so I told her a very little bit more. But I kept it all quite factual and myself very neutral...no anger or blame or self pity. I didn't ever mention OW.
What surprised me was how much everyone already knew about the extent of my H's drinking,
A few colleagues said hello only, but not much else. I don't think they knew what to say. But that's OK.
One person ignored me completely, and didn't even say hello. I felt a bit sad about that.
I also did some work with MIL, and saw some colleagues (that are also more like friends). They were all very sad, one said that he felt like slapping my H when he heard what he'd done. Anyway, I tried to stay calm and neutral then as well.
