I [16F] live with my dad [46M] and his partner [around 30F]. She's very likely the woman he cheated mom with. I don't know what to do.

I moved with my dad to the US this summer. With us lives his partner, who is about 30. We have always had a good relationship. We are definitely not best friends forever or anything but we get along well and we sometimes all go to the movies and events together and things like that, and she's always treated me very well.

The thing is, I am almost completely certain she's the woman dad left mom for and caused the divorce. I don't know know so I don't want to hate her for no reason, but I mean, I think she is because when I younger and the divorce happened mom would sometimes talk to her sisters in person or over the phone and I would hear glimpses of "he left me for a young student", "he cheated on me", etc. I don't literally remember what she said but it was very much along those lines.

Obviously back then I had no idea what was happening but now it's obvious that they divorced because he was unfaithful, and I'm pretty sure they have stayed together all this time.

After the divorce I would stay with him some days and even though she was never there, but I knew he was in a relationship with someone, and they definitely met in our home country, she's not American.

So, I mean, it could totally be someone else who is also young for him, but it seems more likely to me that they have stayed together all this time. i don't know how long they've been together, though

So, I don't know :/

What should I do? Should I ask him? Should I shut up forever about it? What should I do if mom ever asks me if he has a partner or something similar?

tl;dr: I have reasons to think my dad's partner, with whom I live, too, is the woman he cheated on mom with years ago. What should I do about it?
