Sorrow

My girlfriend and first true love broke up with me on Wednesday and I felt the sorrow rushing trough my entire body from that moment on. We were having quite a few fights over matters that really didn't matter, and the whole thing culminated on the night of her birthday. It was truly a wonderful three days since I came to Zadar. We had such a great time, and I will never forget the sparkle in her eye the morning of her B day when she seen me on her doorstep holding a heart shaped Tiramisu cake. It even had the candles lit on so she can make a wish... I only hoped that wish was that we can be together happily ever after.
Sadly the truth was she was no longer feeling the same. She was hoping thing were going to get better once we came back to Zagreb together. I noticed the changes and they keep bothering me, but I never thought things would end that night, at lest not after all we've been trough and all the magical time we spent together.
I got mad that night over something stupid all out of jealousy and ended up saying to her to call me when she starts feeling the same again and went home. The next morning I gave her back the key she had given me. The key that opened her heart for me and I found my self on the bus to Zagreb.
The next few days were an agony comprised of with tears, sorrow and disbelief that a think so beautiful could end so abruptly.
I wanted a second chance to make things better but she thought it was not fear toward me if after giving me that chance she again ended up feeling the same and going to the sorrowful brake up again.
Yesterday she called me and told me she wants to come to Zagreb and wants to see for her self if things can go back to the way they were. She told me that the pain of loosing me was too strong and she never cried over someone for three day, everything reminding her of me...
I told her I was ready to take that risk but am frightened of the outcome, I am terrified of going trough this again. Is it fair towards me?
