I'm not a long time poster (just a long time sufferer), but I say hear him out. If he has some questions and wants to discuss things, at least he's engaged in trying to find some answers. You shouldn't stuff R talks down his throat, but when he's wanting to discuss some things he's read, I think it's worth your time to see what's up. Again, at least he's reading and looking for answers instead of just rushing into a decision without talking to you. My advice is to listen to what he has to say but be very careful with your responses.
