I still love her and i cant get over her, please help?

So i dated this girl for almost a year and we had the absolute best relationship. We finally became engaged and everything seemed like to be going great until her parents found out that i wasn't going on a church mission like they expected me to. In our religion it was a great sin to have premarital and we did start to get a little too close and we wanted to be good so we both went to her parents and confessed and asked them to help us. They did by breaking us up, shipping her to a different state to live with her sister, changing her cell number and deleting her facebook so there was no way of us communicating. It was extremely hard for the both of us and we did find a way to contact eachother but her parents brainwashed her into believing that if i really loved her the way i should, i wouldnt have gotten close to having before marraige. I really do love her and we just got caught in the moment. but now she refuses to talk to me and makes me feel like a criminal. I miss her so much and its been almost a year since her parents broke us up and its still unbearably hard on me. i think about her everyday and i've cried almost every night. Now i found out that she has moved on and is now in a serious relationship with a nice guy that is already home off his church mission and that struck me so hard. I miss her and i dont know how to get over her. i want to but at the same time i dont. i still love her with all my heart. we are both 19 and i know thats young but in my church, its easy to get married at a young age. i honestly love her and i dont know what to do... Any suggestions? Please, only serious replies. i really need help
