www.wayoftheplayer.com they have all the material you need on this subject, but just a personal warning if you wanna do this be prepared to possibly lose your friend. I had a situation like this we were both friends, but we both developed feelings as more than friends one night we were hanging out started making out fairly heavily then she decided she wasn't ready to go all the way understandable I was cool about it we made out a bit more then just hung out on the couch she was curled up against me. Even though I didn't get the fclose I was happy with it. After that she would do everything possible to avoid me would purposely look the other way when I ran into her. With that being said if you want her go for her just be mindful of what I said. I'd personally say call her up set up a date escalate and take it from there.
