Model and gaslighting


My question is how does the model work to show the truth when someone is being gaslighted?

Let me give you an example.

Two people make plans for a special holiday meal together.

That evening they have a fight.

The next morning one of them texts the other and asks “do we have any plans today, I don’t want to not be available if you wanted me around”

How does the model work in this situation? To someone who hasn’t been gaslit their whole lives, it might just seem like that other person needed clarification around what the plan was. However if you understand gaslighting, you know that this is a tactic used to throw the other person off-balance and avoid commitment and responsibility that was already agreed upon prior.
