Hey, senior high school fag here. My friend said he wants to

Most people now are nicer to him and like him for his humour, but a few months ago, some girl he liked called him a "permanent virgin" or something like that and more. My good friend found out and wanted to beat the shit out of her (in reality, he'd probably just scream at her, but the intent was there), but when asked who told him that he refused to say so to defend her. He talks shit to everyone except for people who are legitimately mean to him and he is too afraid to challenge.

He is a really bad listener and a constant interrupter so he makes a really bad friend when it comes to developing meaningful relationships. Unless he really cares about what you're saying, no matter how important what you're saying is or how passionate you are about something, chances are he won't care unless it's a joke. He is really shallow when I think about him and doesn't seem to think much other than on being opinionated on certain political issues and some other stuff. Honestly, now that I think about it he's a pretty boring person. He must have a deeper side, but he hides much of it probably because he thinks it's boring in my case or doesn't trust others.

He started working out to lose weight and he's dedicated which is good. He is into politics and world events which is probably how we got along. We usually talk, laugh and watch YouTube videos rather than do hobbies together. He can be pretty fun, but he isn't trustworthy. He leaks things that sound bad about people behind their back and talks a lot of shit. I would be fine with that if he only told me since I never tell other people's secrets unless it works out for all of us, but he tells secrets to the kind of people who leak everything to everyone they can. He's gotten fucked over by them before, but despite my advice he keeps coming back for more (though somewhat more reluctantly).

I want to bring up all these faults so that he can make new friends, hang out with more people than just me and be happier. How can I unload this into him and help him change? Getting to discuss his depressed feelings is the first step, but what are some key things to bring up in the conversation? Is it worth it to try to change him? No matter what I say he won't cut contact and stop being my friend (unless I do and say things I would never say in real life). After all we've been through and my feelings about and reactions to the things people have done to him, I have to say that I really care about him and his well-being to the point that I would use violence to help him (that's why I started working out, the only reason I don't even tell the authorities about it is because he begs me not to and prefers to maintain the vicious cycle). Can I actually change this guy's life?

tl;dr My friend is depressed and needs help. I want to talk to him about it tomorrow. Are there any key things I should or should not bring up?

Tell him his life matters to you

Really this.

OP is the only person who can say this and it will make a hell of a big difference.

Let him vent and if he doesn't want to listen to you then be abrupt.
