My heart is broken

WE were m23 and f20. it's been one month since the breakup almost. I know I should focusing on moving on, but I devoted so much of me into her.

As in she knew so much about me. I truly felt she was the love of my life. We dated for about 8 months which in the span always were together.

But after I had a suicide attempt she told me it was my fault for not going to her… but it's hard for me because at the time I didn't want to hurt her. It would of killed me to hear her voice knowing that was in my head. She also ended it without like heart break, she just threw what he had away.

I guess last thing I wanna add is should I attempt to fix it or just accept it's gone for good…? We haven't talked in 13 days…
