Being friends with an ex girlfriend in order to get her back?

I tried all that I could to get her back and she said that maybe later we could be together. She wanted to be friends and I agreed. I still want her back and I am wondering if I should continue to be friends with her in order to get her back? She once said she loved me and we were each others' first. What should I do to get her back? Thank you.
