I need help.! Boy problems. . . I know this is REALLY long but I need help with this.?

Hi my name a markeeta and I'm in the 8th going to 9th. I go to an elementry skewl right now and I will soon be leaving to go to high skewl. Bt there's a little problem. My ex boyfriend (let's call him "D") D and I are on a break right now. A little mor background information: last summer of 2009 m and him started to get to know eachother more and developed a realationship. Soon he told me tht he waz falling in lve with me and of course I said the same. Then like a week later he txts me tellng me to call his girlfriend (who tld me he broke up with) and tell he tht nothing was going on between me and him. I kindly told him to f*** off and never speak to me again. And during our 8th grade year he tried his hardest to gt me bk and after him convincing me he wasn't going to hurt me anymore I took him bk in less than a month. Thing were great in the begining. I started catching him flirting with other girls all around skewl. So we broke up two more times. Our last break up waz wen I found out tht he waz seeing his ex girlfriend tht we had a problem with over the summer. Bt we gt bk together then broke up again. Now we are on a break. We acted like a couple and everyone thought we were. Tht waz until he started hitting on my BEST FRIENDS.! And he thought they wuldnt tell me. He hasn't called or txted me in a week and I'm going crazy. I kno tht I shud be getting over him bcuz sometimes he makes me feel like SH*T. Bt other times he makes me feel like I'm special. Mi and him were suppose to have a summer romance together tht worked this time. Bt it looks like it's not going to happen. I love him (and yeh I kno tht ur probally thinkng I dnt know wht love is so I'll say overly like.!) so I overly like him. I need some ways to beth over him. Like he still flirts with me and tells me he loves me. He's the first guy I've felt this way about or jus really really liked him. I've been crying for the past week over him and. Still read all of the lve letters he wrote me. Wht I'm saying is. Should I give him another chance.? How can I gt over him.? I'm making myself sick. His last girlfriend let him go down on her bt im nt tht type of girl. Bt maybe if I do let him feel me up then things wuld of been perfect. He's nt a virgin. Bt I am and plannng on staying tht way for a while. Bt I jus don't know. I NEED HELP WITH THIS.!
