Pls help me regarding gf?

I had this gf of mine for 6 months. Yesterday my nemesis and his gang of chipmunks ambushed me.. They were armed and i was just bleeding all over.... Just bone breaking. The next was heart breaking... SHE CAME AND KISSED HIM, TRAMPLED ME AND THEN HE LIFTED HER!! Pls if some one understands me then pls tell wat 2 do? I still love her.. Feel like killing him.... She always cared fr me (i am sure abt dat) ... And now this?! Now m unable to attend school due to injuries and also have nightmares. Wat 2 do? She always cared fr me (i am sure abt dat) ...
