How do I report a case? pls help?? is it too late?

I'm 24 years old and I want to report this guy in my cl for . i met this guy back in august, he's 26 and he's in one of my cles and we became study partners. I dont and didnt like him in that kind of way besides he has a girlfriend. The week before last I went to his apt to study with him and that's all we did was study and I left. Last week he asked me to come over and watch movies with him (I had to move back home with my parents because I got laid off from my job and they were telling me not to go there by myself and that I needed to be careful but I went anyway).As soon as I got there he told me he wasnt ready for me to come up. So I told him I was just gonna go back home then he said no he was ready. So I walked in his apartment and was excepting to hang out in the living room and watch tv but we went into another room which was his bedroom and his lights were off and his tv was on. He layed down on his bed and I just stood there and told him to lets go back out to the living room and he kept asking me if I was scared (this guy is an african from Liberia and i've always been warned to be careful around africans because they can be sneaky, no offense to any african reading this).I sat in the chair beside his bed then he said i needed to loosen up so i took my shoes off and put my feet up on his bed. before this he had never hugged me or touched me before. he leaned over the chair I was in and started touching my and I asked him what the hell he was doing then he held me down in the chair and got on top of me and he's bigger (muscular) than I am and I couldn't get him off of me and i had on shorts and he started reaching down my pants and i was doing all i could to get him off of me and get my cell phone out my pocket an call for help. he unzipped his pants and pulled my pants down and he already had a condom on and thats when he started to me and he a had my hands held down and i was trying to bite his face to get him off of me. when he got off of me i put my clothes on an got out of there and he had this stupid smirk on his face and he followed me outside to my car. i felt so stupid when i got home cuz my parents warned me not to go there even though im grown and can make my own decisions. the next day i called him and told him he needed to apologize to me and i wanted a real apology or i was gonna report him then the day after that in cl he apologized and said he'd never disrespect me again and stupid me I let it go and forgave him but I still didnt feel right about it. so that evening i sent him a text msg asking if we could meet face to face to talk about it and he said no because he was going to NY which i didnt believe so i said ok have a safe trip. two days later i sent him a simple text msg saying "hey, how's NY"? and i guess he really didnt go to NY because his gf had his cell and she lives in atl, so he either went to ATL to see her or she came here to charlotte to see him and asked me who i was and I said "nvm" then she sent me another txt asking "why wont u tell me who u are" then I said "I guess i have the wrong number" then she sent me one back saying that the guy said he doesnt know who i am and i said "ok"then she called my phone but i didnt answer cuz i was getting ready to go out with my friends. so i text his phone back saying "if he doesnt know who I am then he's a liar". That really got to me, he took advantage of me when i dont even like him like that and he knew i was interested in another guy and now he' saying he doesnt know me. WTF? if he was an honest person he wouldnt have to lie in front ofhisgf. so i called his number and he didnt answer and left him a msg asking him why he's lying and saying he doesnt know me and i called him a liar. he called me back about 20 minlater hollering in my ear saying "didnt i tell u to never call or text me again!!!???? I said "no, wtf is ur damn problem, are on drugs???" then he hung up on me. then i sent him a text msg back saying that he's a dirty *** liar and rapist and he better not say **** to me again, etc.. then the next two days I called him and left him msgs that I was reporting him for then this past monday he sent me a msg saying i was a "stocker" , i guess he meant "stalker". idk where he got off callin me a stalker when the whole time i was gonna forgive his *** and report him and he said he was gonna tell our professor that I was "stocker". I told him no one is stalking his ugly *** and that i was reporting his *** for and that my parents were with me (i havent even told my parents yet and dont plan on telling them, ive only told my friends and i want to handle this by myself).I still have to see him another eight weeks in cl :(
