Yes, I'd agree. University life can be very exciting, lots of groups, lots of new people. This sounds hard, but can I suggest too that you make yourself an interesting life during the time she's away? She'll come home full of her new experiences, you need some to share with her too. If you stay home and fret about what she's doing away, it can be destructive for both of you. You start a new hobby, make some new friends, join a group, you'll both have something new to talk about when you do meet up.
