Im dont understand... Im a young interesting , funny , with sense of humor , smart (not a nerd) , sports guy and a nice person but yet i feel like most times everyone just call me or text me when they need something but rarely someone calls and say ``hey wanna go some where sometime??`` Nop. I just dont understand why??.. In mine entire life if been a dawm good guy if someone falls im fucking there to help but yet anyone cares about me . Is it my folt for being to nice?? Girls look at my and see a... skinny , almost sord of good looking guy but i dont understand think i am a good looking guy , im not a dawm model but i not the fucking troll under the bridge . In the all world i have only 3 or 2 true friends and the rest are just some losers and fakers ..
Im simply trying to have a nice girlfriend and some friends (true friends) .
 I want some advices what whould i do to make this better???
