OP, this is one of the rare times that you're going to have to ignore the advice most people give here. They're Americans and, no offence, don't really know what the British university experience is like. (Likewise, if I didn't hear about it all the time, I'd be totally ignorant of the American university experience.)
In British universities, things are quite different socially than American ones. For example, we have no dorms here. They are halls of residence and although being very similar to American dorms, the main difference being that each student has their own private bedroom with a single bed. This means ****ing is difficult and sleeping together is impossible.
And British universities aren't ****fests like American ones either. There are a lot less parties in the halls of residence because students here can legally enter bars and nightclubs at 18 years of age, and do because local ones offer good student discounts. (In fact, in most places, they are less strict on age; when I was 16 it was the norm for people my age to go out to the pubs and bars in my town.)
Plus you have to take the people attending the university into account. Again, it is different here than in America. Here, most people don't go to university instead taking up full time work once they finish school at 16 or 18. That leaves mostly only those who wish to excel academically. Basically, there is no such thing as jocks in British universities; your typical male university student is hardly the type of guy that gets laid all the time.
So could you rely on her not to cheat? Well, just because she's at university doesn't mean she'll be having her vag pounded every night. There is surprisingly little sex going on at university for people who are not in exclusive relationships. However, she will be hundreds of miles away from you, so she'll get lonely and she'll be horny. Women are the same all over the world and a horny lonely women will cheat.
Maybe if you were going to see each other every weekend it might be different...
