Why can't i meet the right girl?

Ok... I always seem to get involved in relationships with these crazy ladies.. they are either alcoholics, tail waitresses at casinos, or y blackjack deals... Why can't I find a hot girl, thats nice too??? I am a good guy with an edge.. I smoke cigs, pot, and i drink on the weekends.. my issue is that most "nice" girls look down on that behavior, and the girls that are into that behavior are really into that behavior and overdue it.. Its so unattractive when a female shows up at your door fall down drunk crying cause her cousin was arrested or DWI and she smells of a hint of urine.. very un attractive.. or a crazy girl that will call u names and treat you bad and LIE cause shes really not at Kellies for dinner but shes at a bar getting hammered with randy... Why can't I find the right girl??? A NICE girl with a little bit of bad, but just a hint.. a touch.. not a crazy burnt out liqour drinking psychopathic crazy...
