Its long but i don't know what to do?

okay so i was playing this game one time online and this was getting called a slut so i stood up for her and then after that we just started talking all the time what i didn't know was that she was in a sort of online relationship and after 2 weeks they broke and we had a really gd chat from what i had seen she was a really nice girl and fit lol, and she liked me and my mate told her i liked her and then she asked me out and i said yh, the first month was great, and then she showed me another pic and she looked totally diff and she said it was because the other one was from a long time ago so i bugged her a bit saying just be honest with me about what u look like and she said i am so i said okay (because she was getting bad tempered with me) 2 months in i said i don't believe that pic is you and im not putting it with it no more and i went then she said okay ill show u a real pic of me so she showed me six and she said the reason she didn't show me a proper pic was because she was asian and she thought i would dump her and then she started lying to me about stupid things, ow and the start of relationship like a week in i caught her flirting with someone else, after 3 months we kept breaking up and i kept leaving but having a fight first. and then i give her another chance she promised to stop lying to me and then we started talking less and i said are u dating someone else and she said no im just busy and i said why are u typing slow then and talking les and she said she would change she swore on her sons life ddidn'tchange swore on her dads grave didn' tchange and so on with her brothers she did have a reputation with flirting with alot of ppl and she had dated over 91 people and she was 21 and a bi sexual, and then 4 months in i asked her to marry me hoping to fix our problems and bbecausei was in love with and wanted to spend the rest of my life with her and then when we broke she would say she was gonna kill herself and then she would come on pretending to be her sister and saying she is dead, so at one point i had enough and i called her stuff for example u murdering twisted whore ik its wrong but she did kill someone and she really pissed me off, and i said i had met someone else and she said she had met some other girl and called me a small dick ugly **** and never will get another gf, we haven't talked in a week and i really want to talk to her and ive done everything i can to contact her but she wont give me a chance should i be wasting in my time? does she sound worth it? this is me the one she called a ugly **** ik shes right http://pulse.yahoo.com/_7DBCVLBSZH63VNDNRREJ25WXCQ/album/photos/506490
