Likelihood a girl wants to cheat on her bf with me?

So we work together and she's really flirtatious and laughs with me all the time. But, she has a boyfriend that she is planning on moving in with in a month, so theyre definately really serious. Though, when I asked her how she felt about it, she said moving in would make it harder to be "sneaky". Now ive never knowingly hooked up with a girl who had a boyfriend so im really scared about making a move or anything since it could make things at work really awkward but i like her and am not getting any at the moment so why not? Also im moving at the end of the summer so im not even looking for anything remotely serious so im all for it. What are your all's thoughts and do you think its even likely that she may be up for it?
