<human>: Condense the text into a few key points

This is the most painful experience in my life. Although this is not my first girlfriend this is definitely the most serious one. We have visited each other and met each others family's frequently. We have been pretty good match for each other, but all of a sudden she completely cut me off and told me that there has been a "build up" for her and that she never wants to see or talk to me again. She screamed at me many profanities for trying to contact her about a day after the break up. She keeps saying that I have been mistreating her. Although I wasn't absolutely perfect to her (Avoiding her at times when she throws "tantrums") I really did care about her and love her on a level as if I was going to spend the rest of my life with her. This is the most hurt I've ever been. It has been five days and all I want to do is hear her voice again.

Is there any hope of me hearing from her again? Should I try to contact her again? Should I have a mutual friend contact her on my behalf?

I'm so confused.
