How can i win the love of my life back?

i was a terrible gf. controlling, demanding and manipulative (please no need to comment on that, im hurting enough already). we have dated 2 years and its been almost 3 months since the break up. ive hurt him a lot but we have remained friends. last night i drove him home after seeing a movie but i was exhausted so he took me out of the car and we walked in the cold weather and he made me run and would pick me up. he said i have to be friends with him first and nothing else before he reconsiders. at my lowest point i asked for thinking its the way to keep him and he said he doesnt want to disrespect me like that and wants to be one of the special things we would do IF we got back together. if i dont call him for a day he would call or text me. i love him so much and im slowly changing for the better. but what else can i do. i dont want to give up so please dont tell me to move on.
