Oh yeah, those are good points.

Don't stop your life due to his depression. Continue to live your life. If he doesn't wish to go out and take part in something... don't get upset with him about it, just say ok, that you'll try to be home around X-time and that you'll contact him if things change - ask him if there's anything he wants/needs while you're out.

If he gets upset about that - remind him that you need to live your life too. When I'm really down, I'll be upset with myself for not going out - but I never get upset to hear that other people are still going out. I WILL start to get upset if they give up on me and never invite me out anymore though. That tiny little "Hey, we're going for dinner on Friday, want to come?" reminds me that I am cared about, and that those people are there for me. I usually say that I'll let them know on Friday because I'd like to but don't know if I'll be up for it. (Personally, if I have a day where I am up for doing something, I'll contact someone pretty quickly to see if they're free - because I want to be taking part in life and I don't want to be abandoning everyone).

There is a lot of fear that people will continue on with their life and leave you right out of it. That they'll forget about you, or that they'll get too angry with you not being able to do things. And quite frankly - most of us who have that fear have learned it because it is what typically happens.

So live your life, but reassure him that you're really looking forward to when he's up for taking part in it again. Don't stop inviting him out and asking him to do things, but don't get upset or annoyed or disappointed when he doesn't. Because that just hurts us more. We tend to know if someone's going to be upset anyway, and we feel a huuuuge amount of guilt over it, so the more casual the invitation is the better.
