Girls. HELP!!I screwed up my best friend and I am now really miserable. How do I get her back?

I am a 29year old photographer and have had a lot of women..it was just fun and all. But I really care for this 24year old girl. We have known each other from school days itself. She used to be my best friend and I even used to tell her about my exploits abt other women I had in bed. She seemed to enjoy it. She modeled then but never did nude art and was always uncomfortable with it and refused to pose for me then.That was during our college days. We kept in touch through phone and net. Nothing happened. She always maintained her distance but was really a good friend but I wanted more.Few months back I learned that her modeling career was not going so well. I asked her to pose for me & this time she agreed. We did 4 to 5 sessions and I asked for a nude art session with me but she bluntly refused. I persuaded her telling it would give the much needed boost to her career but actually all I said to her was a lie..I only wanted to see her body naked.
I invited her to my apartment and made her take strong drinks till she was tipsy. Then we did the photography. I made her pose provocatively and then finally once more I begged for some nude poses. This time she agreed. The drinks and she herself nude made me lose all my control. I fingered her and she liked it. With a little bit of force and tugging from my part she ended up in bed with me. but I am sure she enjoyed every bit of it. She was a virgin and later she was crying and all in the morning. Ok Guys its all my fault but I still love this girl. She has asked me to go away from her life. How do I convince her that she was not just another women that I had my way with. (well That’s how she puts it). I miss her badly. At least I need her friendship back. She even refuses to talk to me.
How can I get her back? I know I acted crap. But I love her. Just tell me how do I approach her. She is not even responding my calls...and please dont make me more miserable I know I acted carp..If you can think of any good ideas to make her fine ..please tell me..I love her so much.
Please .I am asking for ideas to get her back and if you want to critise just go on call me a bastard or whatever u want..but give some good ideas to get her back..
