I’ve mentioned the ROTS novelization in another thread, but I think its material on this topic is also relevant. The Jedi that Padme trusts is indeed Obi-Wan in the novelization, and she does meet with him in her apartment just like the script excerpt RogueLeader shared, which leads Anakin to sense that he has been there and confront her about it. The idea of Padme hiding something from him is much more prevalent throughout the novel.

On the topic of Anakin not tracking throughout ROTS and having different motivations at different times, perhaps dialogue from the ROTS video game could be used to supplement certain scenes? In the game, it’s the opposite of the novel; Padme is not in the game at all. Anakin’s fall is entirely based on the hypocrisy of the Jedi. For example, the game has a full-on fight with Mace and they have quite a bit of dialogue that is not in the movie. They argue about Anakin drifting to the dark side and Mace/the Jedi betraying their values. During the fight with Obi-Wan, Obi has extra dialogue trying to turn Anakin back to the light, with Anakin refusing the Jedi’s way of doing things. Perhaps some of this could be spliced in to supplement Anakin’s fall.
