You need to relax. She's just enjoying settling down at uni (just as you presumably did when you started your first year). While you obviously want to know she's doing ok, that doesn't mean you should be telling her when she can and can't go out, who she can spend time with etc. because, as she said, that is trying to control her. If you trust her, you'll know she won't hook up with another guy or anything like that. I know it's tough (my girlfriend of almost 2 years has just moved away for a year), but you've got to allow her time to settle in and accept that she won't always be around to talk to you... All you're achieving at the moment is driving her away from you rather than bringing her closer. After a couple of weeks, once the dust settles, she'll have more time for you, but you've still got to remember that you're not the only person in her life, and there are others she'll want to spend time with as well.
