When do girls cheat?

Anonymous
I am 21 and currently in a serious relationship, it's not my first girl but definitely I have never been this involved with any other girl, she's 3 years younger, before me a virgin and I am even her first kiss. I believe we are both madly in love and experiencing really strong feelings only growing as time pass by. We have been together for almost a year and since I have never got this far and this deep in a relationship I feel vulnerable.
It does not seem like it is ever going to happen, but just cause it would probably destroy me completely I really need to know when and why a girl would cheat on the perfect boyfriend, I heard this story before and I'm really worried that at some point she will want to try "new things" and leave me for experiencing other guys since I'm the only one. I can't blame her if she decides to do that but I would still get torn apart.
