I dated this really amazing and kind girl for two years and then broke up with her last November. Our relationship was really the best one I ever had we had amazing sex, never fought each other, and always listened to each other. She fell very hard for me and though I loved her I wasn't ready yet to be in a relationship that could be headed towards marriage. I acted slightly indifferent towards her for most of it though I always treated her the right way, and that put me in the driver's seat. I became slightly unhappy wiith her because I was in Madrid and became interested in other girls while she was still in the US studying. The long distance became difficult and I decided that at age 22 (shes 20) I wasn't ready for this mature relationship that both of us clearly could see heading somewhere into the future. I never cheated on her and she never cheated on me, but being a young man I really wanted to try some new things out.
Anyway I broke up with her kind of suddenly in November and obviously by January I was pining to get her back when nobody could even come close to measuring up to her. We started talking again but I became almost obsessed with how much I needed her and just became way too desperate. I eventually calmed down enough to convince her we had a chance and she let me visit her. I visited her in March in London where she was studying and it became clear that she was not ready to be with me yet and I was unable to control my emotions and deal with the fact that she didn't want to be as intimate and loveydovey and that we needed to start over again and that we were clearly in different places. After all this we decided to wait until the summer to start anew but we would be single for the time being.
It's clear to me that my mistake was that I became way too intense about getting her back and freaked her out a little bit. I just assumed that because she used to love me so much more than I loved her that she would want to hear that but now things are different it's almost like me being breaking up with her snapped her out of a spell or something where she was head over heels in love with me. The only thing I want right now is to return to that place we were in where she loved me very very much and wanted a future with me. How do i do it?? Do i have to pretend to be indifferent when every particle of my body is screaming out the exact opposite? She wants to continue talking with me for the time being, but should I give her the cold shoulder and give her some space after the anxiety filled and stressfull weekend we had together in London?? How do I get her back?
