Ex girlfriend, should I continue to walk away or try for her more?

I'm going through the exact same thing. My b/f and I dated for almost 6 years.. were engaged and everything.. i got drunk and said mean stuff to him.. he broke up with me and now he wont talk to me at all. i love him more than anything in the world.. im wondering if i should keep trying to salvage our relationship, or move on.. i can't make myself give up. i'd say if you truly love her, and can see yourself spending the rest of your life with her.. keep trying. best of luck to you.
