Get EX back..need responses please?

So me and my girlfriend are split up so that we can establish what brought us together in the first place..our friendship..so its been a week and she asked me how i feel and I told her that everything is great, I feel better, like my old self, and im doing fine. I asked her how she was and she told me pretty much the same and that she is happy and ecstatic about our new friendship..I asked her if she would like to take it a step further again and she told me she is not yet at that point because she is still waiting for the "spark" that brought us together in the first place. We talk everyday on webcam at night for about 45-60min. so she knows I'm still here. She texts me everyday wanting to talk. I do not text her unless she texts me. And when I tell her I am busy she asks what I am doing, who I'm with, and if I met any new people. The thing is I don't think she is actually going to get a "spark" with me unless I am actually not there. I do want to be her bestfriend again but also her lover. And I do not think I can do that by talking to her everyday because I am still her technically. What should I do? And most importantly, how should I say it to her that I would like some time out without sounding uninterested in being with her again but not giving hints as to what I'm planning (which is to ultimately get back with her?)
