LDR girlfriend stopped saying I love you back for the last few weeks, but says everything is fine when I ask her. What should I do?

we were only a few months together before we became an ldr. we've been in an ldr for 9 months now. she plans on coming back home after a year since she decided to continue studying here, but by how im seeing it, it seems she's having second thoughts maybe? I can't think of any other reason. could I do anything other than wait for her to tell me whats wrong? she hasn't been completely distant to me, she still shows that she cares. the one thing I noticed is she doesn't say I love you back anymore. we used to say it to each other every day, especially before we both go to sleep.
