try to be there for him if he's sad, then he'll automatically listen to you and you'll start exchanging ur problems and sadness together .. it usually works for me. and if he doesn't want to talk, tell him some of ur problems and when he sees that ur trusting him he'll start trrusting you as well. by doing this ur not burdenning him with ur problems everyone needs a shoulder to lean on sometimes, and tell him that u hate life without him. try the stuff, and if he doesnt start talking to you immediately dont panic some ppl take longer to build trust and to open up. hope this has helped you
