My best friend came over to my house just to chill out and drink a little bit. After a while he got really drunk and went into my bedroom and laid on my bed, ripped his shirt off and told me he wanted me to anal him. i told him i wasn't gay and i had a girlfriend but he didn't care. After a long 4 hours of him trying to get me to have sex with him i gave in, regrettably. since i wasn't drunk i remembered the whole thing and im pretty sure even though he was wasted he remembered too. The whole time he was moaning and telling me he loved me and sucking my dick i just thought i was helping out a friend. After we were finished he asked if i would give him a ride home i said sure and did what he asked. The next day at school he came up to me and said he enjoyed last night and he wanted me again. i really don't want to do it again. The next day comes and i didn't go to school because of family problems. i needed his help watching my little brother so i texted him and didn't get a reply i phoned him and he answered and then hung up on me. i don't know what i did to make my best friend hate me so much. Last night he calls me for the first time in a week and says he needs me to come over for just 10 minutes i said fine (my intention was to confront him and apologize for whatever i did). So i headed over and he greeted me at the door. he looked like he always did but i could tell something was wrong with him. I walked into his house and sat down with him and was about to say something to him when i noticed his dads pistol on the coffee table i asked what was going on and he told me he wanted me to shoot him and he broke down balling on my lap i asked why and he said because he is fed up with living and that everyone hates him and i just didn't get it. he was the cool kid everyone wanted to hang out with. he was secretly gay and only i knew it but i don't judge. So after he stopped crying he asked me if i would do it. i said i cant and i wouldn't. He said if i didn't do it for him he would do it himself. i'm extremely worried about him now. he stopped answering my texts again and he wont answer my calls i feel like i did something to him and i feel awful. and what makes it worse his parents are out of town for a month and he has no close relatives so he could kill himself if he wanted to no problem i just need some advice on what to do to possibly save his life.
