Do you think she will come back soon?

Hey All,

Im just looking for some advice on what I should do in this situation...
My girlfriend of two years recently went on a break (started by her) as she felt being with me she was starting to loose her independantness and felt like we were becoming an old couple also she needed some time and space to figure out what she wants and etc.....
It went on for a month (worst month of my life) very little contact, but when she contacted me it was stuff like "i don't want to hurt you you deserve so much better etc",

I am so heartbroken over it cause I really don't deserve better I would die for this girl! We had the best relationship ever! Never ever had arguments of fights, always trying to keep it interesting and new and were completely head over heels for each other, without sounding like a doush I was a great boyfriend and I helped her so much in her life, I wasn't controlling, grippy or anything like that...
Anyway, we met up the other day and I wrote her a big letter as I wanted to make sure every word got across, the letter explained that this was the worst and last thing I wanted to do but I believe that the break wasn't enough for her she really needed some no strings attached time e.g. Me letting her go so she really had her time... But before I gave her the letter she told me something right out of the blue.
Firstly, I asked her was the reason she hasn't broken up with me was because she was afriad to loose me her answer was 100% yes. She then said that she tried to start something with a guy just to see what it felt like to herself and if she could handle it.... She said she felt absolutly terrible after it and felt sick, she said why in the world would she think that something with someone else would be better than me. She also said (crying) that it sounded silly but she can see herself come running back to me!, but she still needed time to firgure herself out
... I was obviously confused as to why all that can happen but still we arnt together properly?!....

Anyway I gave her the letter and she cried for about half an hour, we could have got back together then and there but we decided this was the best step for our relationship (letting each other go for a bit) as it will make us stronger in the future, she said she is still IN LOVE and always will love me, but spiltting up is what needs to happen...we said we would still catch up and call whenever we feel like it. No texting as we think it just starts annoying little mind games.

Heres my question... It still feels like a break for me, I still feel like I'm in reltionship. I have trust in her that she will come back (do you think she will?) but until then I can't help but want to call her everyday just to see how she is and how her day has been, and I get the feeling that if I don't call her she will think I have moved on but at the same time I don't want to think she has moved on, its been almost a week since it happened how long do you think I wait until I call her? Is she thinking the same way as me? Is she just waiting to see what I do?

Sorry for the amount of info but I was hoping to get the complete story across...
Some advice would be greatly appreciated

Thank You All so much...
