Girlfriend broke up with me. were talkin but i dont know what to say in order to get her back?

ok lets start with we dated for a little longer than a year and half. we had good and bad times. at times the bad was horrible but it was worth it. but anyway we broke up not to long ago and about a week later we got back together. then not long after we broke up again and she wanted to be back together and so did i so we tryed it again. it was wonderful. i loved the way we treated each other and i was super nice instead of just being a guy i was really bein her boyfriend for once. i was considerate of her and done a lot of things for her and really learned how it felt to be a good boyfriend. i was absolutly without a doubt in love head over heels. but soon after we got together i noticed she was actin wierd like she was avoiding me. i decided to ask about this and she wouldnt say anything. i thought for a little while that she had found someone else during our last breakup but shes the one that wanted to get back together in the first place. well shes the one that admitted it. but anyway when i confronted her i found out that she had lost the spark for us last time we broke. she was tryin to make it come back but couldnt. about a week and half later we started talkin like just friends talkin. she said give me time to decide how i feel about this. now a week after that we talked and she said she felt the same. i proposed we just be good friends for the time being and see how it goes. that night she said that she was feelin great about this and really opened up to me again like she used to be. and at the end of the night she said if we did this a month or two she would deffinatly want to start dating again. now heres the question how can i talk to her and be good to her and show her that it would be nice to date again without pushing her and makin her feel like im desperate. i think she truly wants to do this but im just scared of pushin her away by bein around to much. but at the same time its killin me cuz i am used to basically livin together and i want to see her all the time. what do i do. i dont want anyone else i dont want to move on i want to fix this and continue. i want to be happy with her and her only. so please dont just be like you need to move on or somethin like that.
