I don't know exactely what happened 2 u with ur friend or what he did 2 u but i'm deeply sorry
for what it's worth i had almost the same situation n i think that r8 now i'm nearly friendless n it's really hard 4 me 2 make new friendships cuz i don't trust people n i'm not quite a social person
anyway, u said that ur friend was number 1 2 u but he didn't consider u number 1 as well..well the things my friends did 2 hurt me i would've never done 2 them..i thought that they cared as i did, i thought that they wouldn't do anything 2 hurt me especially while knowing that they were giving me deep sorrow n pain but they shoked me.. so i started seeing them as hypocrites, they laughed with me n pretended that they cared about me n loved me whereas the truth was that behind my back they did horrible things 2 me n they thought that i didn't know but i did..i wanted 2 say something about it but unfortunetly i couldn't because it involved other people n they didn't want me 2 say anything so i tried 2 get away from them but they just wouldn't get it ..eventually i started treating them the way they did so i became a hypocrite with them the way they were with me n now i hope never 2 see any one of them anymore
so that's my long story in short just 2 tell u that u r not alone
