Can Long Distance Relationships Work In College?

I’m not going to get into every little detail of my love life but the facts are me and my girlfriend go to two different schools. We visit with each other as often as possible usually every two or three weeks for the weekend. What I’m really looking for right now is some confirmation from all the females out there who have been in long distance relationships that they didn’t cheat on their boyfriends. However if that’s not the case I’d love to know what went wrong so I can do everything in my power to prevent the love of my life from slipping away from me.
