unwantedlove

so this is my first time blogging. ever. there are some things i dont understand in my life, one of those things is boys. there had been this one boy who i have liked for almost six years, and i know i love him. he and i have always been really really close. weve always had eachothers backs and we used to hang out like all the time, but this year, everything changed. he started drinking and experimenting with drugs. when i tried to talk to him about it, he completely ignored me. so i put my trust in my sister. my sister then decided that the best solution was for her to tell his parents that i was worried about him. ever since hes parents confronted him about my worries hes hated me. he wont even look at me anymore. i still really like him and even love him. i know that may sound crazy but its not even that i want him to be my boyfriend, it that i care about him so much. i really do love him and all i really want is for him to be my best friend again. so what should i do? how can i get that relationship back? how can i regain his trust?
