moving on is hard. what do I do?

I grew up in a very shelterd home, I was homeschooled my whole life. my dads a minister and my mom is very religous, I always had good morlas and knew what kind of man I would want when I grew up. My life changed last year when my parents actually let me go to a public school, Its was the biggest time of my life, I was actually making friends and everything was great, then I realised I was the only girl that didnt have a boyfrinf, or at least thats how I felt. I had a few crushes but never once thought about sex. when I would hang out with girls the subject always came up about boys and who had sex with who, and I was ok didnt really think anything of it, I was really good at keeping my morals striaght, for example sometime around homecoming I found out this guy liked me and we went to the dance to gether and we met up at a football game and I knew he was going to ask me out adn I was ready and he did, we walkied around for about 20 mins and he started sugesting places we could go to be alone and do "stuff" and I broke up with him because of that lol. Well... about a month before school was getting out I went to this party and I met this guy and he was really great, He seemed really interessted in me and I was really interessted in him and he asked me out and of corse I said yes, I thought he was like super duper hot. and he tryd kissing me and I'd back away, so he couldnt ( I hadnt kissed anyone before in my life so I wasnt ready to just give it away.) but with in a few hours I gave in and he became my first kiss. and me being stupid later on that night I gave him a handjob. and this all happend in the same day that he asked me out... yeah I know I was really stupid. and the only person I told was my bestfrind.. well, 3 days passed and when I went to school he broke up with me sdaying thta he heard that I said he had a small p*nis!... I never eveer once said said that, and I tryd talking to him and he wouldnt take me back, or even just believe me. and his frinds only trying to stick up for him every time I woul d walk by they would call me HJ, at school in front of peopel. every where I went "hey HJ!" it got so annoying, and I was because I still had feelings for him. a month later I was talking to this girl, she had invited me to her open house and I was going to go, she said that he was going to be at there, and I told her how I still liked him and how I wish there was a way I could get back together with him, and she told me how she had the same problum with this one guy but as long as she keeps hooking up wih him(having sex with him) he stays around, and its great bcause she likes him. and she told me that she had condoms and I could use one, never once in my days did I ever think I would actually be interessted in doing something like this, and so I went to the the open house and I actually got there erly and ended up staying for the whole thing and it turned out he wasnt coming until after the open house, and so she told me I could stay the night so I ended up doing that and him and I ende up going all the was and yeah I lost my v-card that night. then my parents found out and I spent the whole summer grounded and I never saw him till I got ungrounded wich was a few weeks before school started agian, which was during the fair and I ran up to him and gave him a hug cause I hadnt seen him in a long time and he just walked through me and I was like ok. it was lke he hated me now and I didnt know why, so later on I asked him if I could talk to him and he said no, and I just walked away and was like what ever, andI took it really hard, I felt really used and I didnt know what I had did and there was nothing I could do about it. School came along and I ended up having two classes with him and everytime I looked at him I felt naked and disgusted, I hated it. I had somone ask him why he hated me, and he told them he just didnt want anyuthing to do with me. peopel would tell me thta I talked a bout him a lot, and that I needed to get over him and I said I was, I cant stand him all this school year I just kept wishing that somthoing would happen to him cause he was a bad boy and was always out partying and I just wanted him to get caught so I wouldnt have to see him anymore. I kept saying I was done with guys till I was out of school, I dont want to go trough that pain ever again, well he got in trouble and now he goes to juvenille school. andI wont have to see him till next year, and I still think about him time to time, and how I wish I would have never even went to the party where I met him. Sence he's been gone I got a boyfrined and everonce and a while ill think oh he'll be jealus when he see's my boyfriend and I. and sometimes im scared im going to compare things wbetween my boyfrined and him, and sometimes I think of how different the two of them are, I finally got the kind of guy I want that respects me, somtimes I wish he was more of a bad boy but I know how that goes and thats not really what I want and I just wish I could get my ex out of my head. My beast frined even said to me the other day that I cant deny that im not over him, and I dont even talk about him anymore it just came out of no where. I just dont know what to do. How I can just not think about him. how to stop comparing my boyfriend to him, I know I dont want him back, or anything to do with him. how do peopel get over situations like mine.

sorry its really long, I thought if I gave enough info it might be easier for advice, If you think you know a good answer then I would greatly appreciate your advie.
