Just to clarify... What are his problems, in your opinion, and what does that have to do with his marital status?
He's frustrated. He's gay, unwilling to come out for political reasons (he's old), and he feels in his position it wouldn't be beneficial. Conservative (religious) gay men have an extremely tough time with homosexuality.
DO I know that for a fact? No, but it's eerily similar to other men in similar positions.
