Should I keep my parents affair a secret ?

One of my parents(referring to them now on as K) had an affair about a decade or so ago. I was the one who had to break the news to the other parent(referring to them now as Q). Both told to keep it a secret from my sibling, i was a young teen at the time and it was pretty rough. Eventually, my other sibling was told about the situation when they were older. I'm sure everyone in the family could have handled the situation better and these things are complicated and very painful.

Now I'm in my early 30s, my parents are in their 60s. And Today when visiting their house, I look over at K because they're holding their phone a little strange. K had returned from a christmas function and were drunk AF. I see they're on FB messenger talking about meeting another person (referring to them now as Y) and sending kisses. i don't recognise the name. Although from a distance i manage to piece together the name, and i see that they are not friends on FB. Unusual. So i keep an eye out a little more, can't make out what is being said but after K has finished messaging they DELETE the message. Alarm bells are now ringing, to me this is pretty damning. Looking into it, Y used to be work colleage but was fired from the job several years ago.

So here is where it gets a little complicated. For christmas, K has arranged a huge family holiday in another country. Both parents are super super excited about the holiday, other family members are coming too, it's a big thing and we don't usually do this as a family. We are due to leave tomorrow... I told my sibling what I saw, they said the ball is in my court as what to do, they also feel it is suspicious behaviour. Perhaps it was selfish of me to even discuss it with them...but i'm trying to do the right thing whilst dealing with my own pain, as well as the sadness I feel for Q.

I'm starting to think that I should not to tell Q , or even confront K about what I have seen. If K is having an affair... would they be honest with me? if it was true... what happens now? How far do I go with this??Although the actions were not mine, I feel I’d be partly responsible for messing up the holiday for Q and K, as stupid as that seems in the grand scheme of things... Should i talk about it after the holiday? Not mention it at all ?? Would really appreciate some guidance

TL;DR One of my parents is potentially cheating on the other. If I say anything it could mess up a 40 year marriage and the Christmas holiday
