I think we are to monitor ACTIONS. Not WORDS, or MOODS. Because words usually mean NOTHING, and moods CAN mean nothing, or they can mean something, or they can even be COUNTER (in affairs, for example, "GOOD = BAD" and "BAD = GOOD", as it's usually when they've had their OM/OW fix that they are in a good mood, and usually when they're in a BAD mood, there's trouble in Paradise).
I was given this advice, and I think it's good: "Only when her actions align with her words, over time, will you know she is telling you the truth."
