Surprise at work

So i may or may not have been flirting with someone at work that doesn't speak the same language as me. She used to give me candy and i thought nothing of it right. Well, fast forward several months and she is telling me she has to distance herself because she is going to get married. After the following weekend she tells me that she couldn't stop thinking about me all weekend and that they postponed the wedding. I had given her no reason to think about me other than being nice to her, tell her she's beautiful and making some jokes. Today was absolutely unexpected and absolutely phenomenal. I was working on something in her area and we are talking using translator like usual. Welllllll, out of nowhere she says hey and shows me her phone. First photo was in underwear but holy cow, absolutely stunning so attractive. Well moments later she shows me another picture, this time with no top, and my fave gets red af. She then asks me how i felt about the photos and then says how she wanted to show me she isnt perfect. I told her she sure looks perfect 😅. And then we talked a little more about her photos and stuff. Anyway, i kinda feel guilty af, I've been cheated on many times in the past. I really dont know hiw to proceed with this information, i feel like I'm in a movie. Should i feel guilty? Should i tell her we cant talk like that at work anymore(we dont talk outside of work for obvious reasons)? Orrrrr do i say f it and see where things go?
