Should I quit dating a girl if she smokes and thats a red flag to me?

Sorry, didn’t know how to better put the title. But that’s basically it.

Went on a second date with her, walked around a little to a bouldering gym and suddenly she confessed to me that she smokes and pulled out a cigarette. She asked me if it is okay for me and at that time I didn’t know how to handle it because it was a big surprise to me. I told her that I don’t care but it is actually a huge dealbreaker for me. So we continued having a great date. After the bouldering she sat down again to smoke one before we finished the day with a dinner at a restaurant.

She is clearly into me and I like her too, but whenever she pulls out the cigarette it is a turn off for me. Should I tell her or just move on? I don’t want to put pressure on her.

She is nice but I only would accept smoking if it was like a one thousand percent match where everything matches immediately – that’s not the case – though I’d still like to get to know her better. But then I think if it’s worth it if I can’t accept the smoking anyways…
