Not sure how to feel or what to do

Me and a friend became very very close. We became that we were called boyfriend and girlfriend even though we weren't so were decided to say 'ok, lets be together'. The first time didn't work, she said to me that she 'just wasn't feeling it'. Like good friends we worked it out and made up then the same thing happened we were together again but once again it didn't work, she said that we had more of a laugh just as friends but it turns out she love me like she said so many times, she has always loved someone else older than her she met in a nightclub, all the things me and here went through was just her being kind to me. Now I hear her talking openly infront of me about this other guy and I know I need to move on and thats what I'm doing. I just don't know how to feel or how to deal with the fact that she was just 'being kind' to me the whole time and played me for a mug and played on my emotions. Any suggestions on what I can do or say or even not say anything at all?
