Dealing with a break up… Should I try to get him back?

Beforehand sorry for the long post. I want to try to give you the whole story. Im 19, my boyfriend, or well ex is 25. We met online 10 months ago and started dating 9 months ago. He's in the army and he lives on post, I work full time and we live about 45 minutes away so we only see each other from fri night to sunday night. Er stays over at my place. Everything in our relationship was great until about 2 months ago... thats when things started to really go downhill. We are each other firsts, our sex life is really good, we can talk about anything, and we always tell each other that we are each others best friend, and its true. We are different though... we were raised different... i was raised with a mom who was very strict but at the same time she let me live my life and enjoy and make my own decisions. I've never done anything wrong though, never done drugs, never smoked, etc. I do drink but thats because my family is European and well, wine and all that thats like juice for us, however, i've never been drunk in my life. He was raised a very strict mormon, his parents and like very religious. He stopped going to church a few months before he met me. I think our greatest difference problem was the religion. But I respect his and any other religion so I didnt care, he didnt seemed to care much either, he said he had dated girls from other religions too.
Anyway... I have to say at the beginning of our relationship I lied to him, I told him I was like this party girl and that I had some crazy stuff and all that when thats far from true. I guess I just saw my girl friends all doing all this crazy stuff and going to clubs all the time and I wasnt doing it, that when I met him I thought I had to say that so he wouldn't find me boring or something. I know it was a huge mistake, this is the first time in my life I've lied and I regret it so much... From that image I put in his head of being a "party girl" he had so many arguments (i said that before knowing what a decent guy he was), but we got through those arguments.
We were great together most of the time, we traveled together, went on vacations, went to meet one of his sisters for a week, everything seemed so great.
We started having sex after being 4 months together... After that we've had some pregnancy scares and I think that also hurt our relationship. About a month ago I was really late on my period and we thought I might be pregnant, he talked about it, he said he wanted to get married, I said I didnt want to get married just because of a kid, he said he was planning to propose in Dec. So after that for about 2 weeks or so he was talking about marrying like all the time, he seemed so happy, where we'd live, what'd we do... all this plans together... then suddenly one day he told me he was having doubts that he didnt want to get married now. He had a huge argument about it... I was really hurt because even though the first couple of days I didnt really believe him... after a while I got really excited. I love him with all my heart and I'd love to marry him. So I was really hurt and he said he was ashamed of himself for hurting me, etc... so we took a one week break. We talked and I told him that even though I was hurt I didnt need to marry him, I just wanted to be with him, and I didnt need to marry him in order for me to do that, he said he felt pressured but that he still wanted me in his life, so we got back together.
We were somewhat ok for the rest couple of weeks... until Tuesday. It was the day after celebrating 9 months together and he broke up with me. He sent me an email telling me how he had small doubts from the beginning about us, that we felt in his heart we werent right for each other, how we wanted different things (not true) and a whole bunch of other stuff. I was beyond devastated. My heart was just crushed... He is my first everything, but most important he is the first time I've truly loved. I gave him all my heart. I'm a really reserved person, I've been hurt so many times before by the people I loved the most that I just never put myself out there because im so afraid of getting hurt again, so I just think that if I dont let people in, if they leave, it wont hurt as bad. But he asked me to let him in and I did, he met my family, I told him everything about me, I just gave him all, because I thought he loved me and that he'd be the last person to hurt me.
I asked him for another chance... I came clean with the lies I've told him, I asked him for forgiveness and another chance with no more lies or anything. We were so great together, I know that if he'd give me another chance we can make this work. But he said he wasnt going to give me another chance, that we were over, no second chances. That he hoped we could remain friends but he couldnt be my bf anymore, that he forgives me for lying but we couldnt be together anymore.
I kept trying to explain and convince him to try again but nothing worked. He said we were over and that h

Its good that you were honest with him. Just give him time, don't make it so well known that you want him back. Just be cool and trust me if he is truly over you than what can you do, chances are he will think about things and you guys will dating again, BUT never lie to him again about any thing. Good Luck.
