someone unfriended me on snap, I want to ask why, but should I?

I hv a friend, we talk quite regularly in person, but today she just unfriended me, idk why. I really want to ask, but then I don’t want to make things worse. should I ask?

Edit: I hang out w them and two other friends during certain classes, they unadded me as well. I apologised to the first one, I’m not sure what I did wrong, but I apologised assuming that it was something I said and did wrong. Sometimes I say some things that r weird , not directed at them, but I just assumed it was this. I apologised via voice message
