<human>: Can you give me the gist of the text in a nutshell?

Me and my ex dated for about 2 years on and off. We split up for about 9 months at which time she dated someone else. Our first go around I was extremely committed and deeply in love with her. When we got back together last August she realized she was not fully committed to me in our first go around and changed a lot for the better. She apologized for a lot of things and became the sweetest and most thoughtful girl I have ever been with. However, for some reason I was unable to appreciate this. Our life schedules were a little crazy. I had just started nursing school and felt that I did not have time for a relationship. Since I broke it off I now understand that I did not make the girl I love a priority. I thought that just having her was enough. I came to find that loving someone is not enough and that you must show and prove that love continuously. Love is not given it is earned. She says she wants to be friends and that I am her best friend, but I am freaking out a bit because she is going out with friends and trying to enjoy herself. It has not been until this morning that I now know I need to give her some space. I want everything between us to be okay and I want  a quick fix. I know this will not happen. BUT! I do want her back, I do want to show her I care, I want to show her I love her, without smothering her or appearing to needy. I need advice on how to go about accomplishing all of these things.
