Serious answers only! Please don't be rude, but I have a question...?

A little over a year ago I made the BIGGEST mistake of my life. Basically someone was imprisoned because of a misinterpretation & now is on probation & has to be labeled as a sex offender. The situation is this...So there was this dude that I really loved, but was trying to stop things before something got too serious. Well he's a dude with raging hormones & mind you we are both 20 years old so doesn't sound to unbelievable. Well he kissed me against my will & my friend caught him. When she called the police, she falsely told him that the guy tried to rape me & that I was "too scared to say anything." So he went to jail & I thought that would be the end of it. Turns out he actually got a plea bargain which means he would be on probation for like 4 years & he's labeled as a high risk sex offender. This is all my fault because I allowed my friend to tell the police something that wasn't true. She actually did this without my knowledge & truthfully I had NO IDEA she was gonna call the police & file that fake report like she did. Now he's serving time really for something he didn't even do. My question now is, what can I do to get this madness off of him, that way he can put this whole nightmare behind him? Me & my former friend are no longer speaking because I feel this was a VERY vindictive thing she's done. I don't want this guy paying for something he's COMPLETELY innocent of especially at my expense. How can I get the charges dropped? I feel so horrible about what I've done to him, I am almost afraid to face him. Please help me out! I need advice. He's no sex offender & he doesn't pose ANY risk to anyone. What can I do for him? So that he will no longer have to be labeled as a rapist or whatever she told the police?
