I am 20 years old and i am a pakistani girl.anyways i use to cyberstalk this guy alot and he's 25 and he's also from pakistan.the first time i use to text him he really wanted to go out with me but i didnt and because of that reason he became very rude and upset with me.i even sended him my pictyre he wrote u look good.i use to abuse and bother him alot for 6 months.the otjer day i went on his facebook profile and he has a picture with a american girl she's wearing tank tops and he's holding her elbow,thats not fair and also he has a pakistani girl as friend on facebook and he likes her pictures with me he acts rude and he flirts with other girls ,i get so jealous.i dont have contact with him anymore.i also use to say dirty things about myself to him.
