Sure it's completely fixable. Girls love attention and variety. You can worry about her exams, give her support, show that you are interested in this and understand that's important. And then excite her well, come up with smth passionate. I'm constantly experimenting with my girlfriend. In addition to banalities such as role-playing games, we tried various interesting places (a rock concert, for example, or a roof). The last feature - went together in a strip bar, she did not want at first, but then got carried away by this idea. In general, in this Zavistbar there was a room for privates, stylized under BDSM (no hardcore, just an easy game), and it was so exciting that now we try it too
So do not let her get too distracted. And all these emotional throwings are solved by a simple imitation of attention.
