Should I be worried about my girlfriend going to a University?

My girlfriend and I have been dating since her freshman year and she is now graduating and going to ASU, I am a little worried about this. We will be living in the same state and I will be attending PVCC but she will be staying in a dorm for her freshman year. I just want some advice on if I should worry about her at this school with alcohol and partying, and if this school could cause any unfaithfulness due to the guys attending the school? Shes never partied or drank or did drugs or anything like that, but I'm afraid this all could change her and result in me losing her. Please give me some advice. Thanks for reading this.
