Found out that a woman interested in me in class has a boyfriend (in the same class)?

So i started out new classes recently. Then a woman walks in whilst I’m sitting in a group of other dudes and instantly notices me. She was shy, or so I thought at first. Constantly gives me eyes though, tries to get eye contact and always tries to be close to me but my gut doesn’t really seem to like her (even though i do find her attractive). I had two interactions with her where i asked for her name and then later confirmed it. Then last week i noticed some dude staring me down ( I asked myself what that idiot was doing) and so I did some digging and low and behold I find out that not only does she have a boyfriend, that dude is her goddamn boyfriend. And now I’m struggling to comprehend what the hell i should do here. Pretend this never happened? Tell her to cut it out? Cos she's still doing the exact same thing. Im not even talking about the prospects for drama here….
