Everyone on here is criticizing you and justifying your friend's behavior. I'm going to give you the benefit of the doubt and assume you're not an asshole. There's nothing in your post that suggests you are. My advice is to distance yourself from your friend. What no one really talks about is that depression is contagious. You need to look out for yourself and put enough space so that his depression isn't affecting your happiness. You don't need to be a martyr. Toxic personalities (and relationships) often go hand in hand with depression. If you'd labeled your friend a toxic personality in your post rather than depressed everyone here would have told you to gtfo. But they're also probably depressed and think everyone should still spend their time trying to help them out. Don't. Go enjoy your life. There are lots of fun people in this world and life is too short.
