No way! Next time they do that take them aside and say why do you do that to me? Why do you always use me for something and then try figure it out you never know they mite even actually be a true friend after all!
I think he's just trying to be nice by adding you. Since you broke you p doesn't mean he doesn't still want to be friends. If you think he is depressed just ask is everything ok? And maybe he will tell you the truth. I don't know about you but that's what I would do!
