The person i trust the most make me sad like hell

first when i meet you i thought we can be friends but as our friendship grew more and more i notice that you are the person that make understands me and make my life happy. but i did not realize that you are just a backstabber and like to talk shit behind my back. i think you don't even know the meaning of friendship i guess because if you are my friend you will correct my mistakes and not talk bad about me to other people like that. i know all your bad stories but i never talk bad about you to anyone but why must you do this to me i don't know. i have help you a lot and try to be nice to you but this is what i get from you is awesome thanks a lot so call F.R.I.E.N.D
