<human>: Can you succinctly summarize the text in 1-3 sentences?

So my girlfriend(19F) of 3 years just broke up with me(21M). It's a long story and ultimately it is my fault...I take complete responsibility for it...however she was my first true love and the first girl I ever kissed and did anything with...I'm insanely emotionally attached to her and still love her beyond belief and want nothing more then to be with her. However she's already talking to another guy in an attempt to get over me. It's been almost 2 weeks since she left me and I've tried everything to try and get my mind off her and move on, but I can't. I want nothing more then to be with her and show her how much she means to me. But I have a feeling any sort of contact with her is just going to push her further away. Does anyone have any advice as to what I should do? Thank you
