Girl i’ve been talking to recently told me she has a bf

I’ve been working on a group project with this girl in my class and initially we didn’t talk at all but after 2 weeks we started talking everyday over text and face to face. It progressed to her asking me to sit beside her in class, going home together since we live so close to one another and visiting each other at work. There are times when she randomly ask me where i am and she’ll pop up at my location 5 minutes later. But after 2 weeks of this, she suddenly told me she had a bf who is doing exchange at Switzerland and that her relationship is on the verge of a break up as her bf isn’t a good person and that he does drugs. Idk what to do now because i haven’t liked anyone for almost 5 years now and its hard for me to stop talking to her since we’re in the same class
