Please help a broken heart?

My girlfriend of 5 years broke things off with me 6 weeks ago, during that time we spoke 3 times via phone , me calling her to check and see how she was doing. I have tried my best to give her her Space and respect her decision, all the while I have been dying inside without her. 2 Days ago, I could not take it anymore and beared my soul to her, I told her How I was not ok , how i was miserable, not eating, sleeping or getting my work done. I expressed my self to her and how I felt about her, Explained how important she was is to me. We broke up because I was a scared idiot who took to long to ask her to marry me, when that is All she ever wanted to do, I said some mean things to her that were hurful, and she also indicated that I made her feel bad about stuff because i always was trying to correct her. She said that she hated not speaken up about things at times, because she weas afraid I would say that what she said was unintelligent. Are relationship got rocky, and instead of waiting around and fixing the problems like we usually did, she gave it plenty of thought and broke up with me over the phone and left it saying, it was the best thing to do. After I had explaind my self to her, and let her know how i feel, I asked her to please consider us and think about if there is a chance that we can ever get back together. I cried on the phone, and basically left nothing on the table, I just needed to let her know that she is my everything and that I am empty without her. She played it very strong, was firm, did not sound like she was tearing up or anything. She said that she would give it some thought. I told her that by me doing this ( crying and baring my soul to her), I want her to realize that I know what this means, that hopefully we get back together, and within a month I will ask her to marry me, after we discuss the future. She is a very good girl, well mannered and lady like, I was her first everything, Is there a chance I can get her back, is there a chance she is seeing someone else, is there a chance she thinks i am not worth it all. Most importantly what do I do now? Do I call her or do i just wait? SHe knows exactly how I feell about her and that I want her, and want a future with her. Please help. Your words well help calm me down, my heart is broken and I am so confused. The break was not over us fighting or cheating or money, it was jsut becasue i took my time to do everything, and she got tired of it all. Thanks again _
