Hello! I've finally fought my way out of the land of homework for a few minutes! What a lively discussion! I may have a few thoughts... Was he attached enough to Anakin to have kept quiet about it? Or was he more attached to the Jedi Code, as Anakin believed? I think Anakin believed a lot of things about Obi-Wan that weren't true, and I don't think he ever took enough time to really get to know his master. For being "the epitome of the Jedi," Obi-Wan sure had a lot of quirks - for example, his friendship with Dex. I don't think Obi-Wan would have told the Council about Anakin's marriage; he was not a tattle-tale. If anything, Obi-Wan probably would have talked to Anakin about it, letting him know that he knew and discussing the situation. He would encourage Anakin to think rationally and try to convince him to talk to the Council himself, which may have worked if Anakin trusted him more. A lot of things would have worked if Anakin had trusted him more.
