The idealizing sounds like transference. I had the idealizing sort of paternal transference for my marriage counselor at first (and some erotic transference, too). Told him about this, and he's shared more of the real stuff about himself that showed he was far from perfect (like yelling at his kids till they cried, etc.). So it just became more, I guess, regular paternal transference. Which is still very difficult at times (like yesterday!) but I see him as a real, imperfect father and human being now. Which helps.

Have you told your T that his life seems perfect to you, and that's difficult for you? Assuming he's willing to disclose some stuff, maybe he could tell you ways that it's not so perfect? Or even if he won't disclose particular things, maybe just talking about your impression of his life would help, like to get those feelings out?
