look bro, dump your gf and figure out how to get paid. you sound like your 18. hoes love money, know that. work your dick off til 24, stack alot of paper and get a personal stylist. Get SUPER fresh, i mean un-godly fresh. At least 25k on a rolex fresh. then you will absolutely devour any girl that comes in your path and your current gf with be a faded memory.
i tell you this, because im the same way. had the same girl friend. im 26 now, with the rolex, the chain, the bracelet, the car, the club connections. i had to learn the hard way, but you have to realize, girls will get ran through and if you want to date someone in your city, understand you will be eskimo brothers with abunch of dumb cunts. find a girl from a completely different city. that way you will NEVER know who she banged.... (<---still working on this one, its too much fun blowin paper and smashin hoes)
you need a "slam piece" while you are gettin that paper tho. times be stressful and you need that relief.
