Just friend?!?! Confused. Is it possible?

My ex boyfriend and I have been broken up for about 4 months. We were together for 2 years. We broke up because of me. He couldn't trust me cause I lied and manipulated him. I never lied about anything drastic. I would say things to PURPOSELY make him jealous. I had good intentions. I just wanted him to want to spend more time with me and hold me closer. Little did I know that it just pushed him farther away. :/ NOW I know you can't rely on intentions. You never know how the other person will react. But last week we finally started having civil conversations. Before that we would always argue if we talked and he would say mean crap. He admitted that he said them cause of how I hurt him. I can understand that. Well last night he told me I am his best friend. His only friend. We talk 4 - 5 hours a day. He came over and hung out with me and we just talked. Do you think it is ever possible that we could get back together? I love him and I miss him. It hurts to know we are just friends...but I will take what I can get. I have been told "You are NEVER in the friend zone with a guy." Is that true? Should I still dream and hope for another chance or just give up? I don't know what to do. Please help.
