Feel like hating her?or missing her?

I was in a relationship with a girl for about 2 years,granted this past year we were having problems but what couple doesn’t I actually thought we were getting better but then she wants to break up b/c of personal reasons relating to her family she tells me that she doesn’t want to be in a relationship b/c she doesn’t know what she wants.It was the hardest hit to the heart I’ve ever felt.Then I find out a few days later that she’s already in another relationship and going like wtf?!Thought she didn’t wanna be in a relationship and that she wanted to focus on school and her family but turns out she can’t stand being single so she leaves me for another person.Honestly I just wanted to die I still do b/c now she won’t even talk to me everytime I try to get in touch with her she thinks it’s drama and she’s always in the “middle” of something EVERY single time I try to talk to her no way thats a coincidence anyways right now I just feel like crap,I even wanted to just be friends with her but even that she won’t grant.She always said a guy (me) gets over a girl (her) like nothing,but turns out to be the opposite in my situation she’s moved on forgotten about me and just doesn’t care,or at least she shows that she doesn’t care. Honestly I’m lost on what to do I’m still in love with her,not a day goes by I don’t miss her but she won’t even give me the time of day.I just hope my short term memory kicks in and makes me forget about her forever and forget she ever existed.Is there anything like that?Shock therapy or something to make me forget about her?I can’t stop thinking about her but I want to.Obviously she don’t care about me anymore.I hate that she lied to me,I hate she moved on to another relationship in 2 days I hate,that she won’t even give me a chance to talk and I think I’m starting to hate her which is something I would have never ever thought of but she hurt me real deep inside as if I never existed and/or mattered to her please give me advice on how to get over her I’m begging. =’(
