Good morning fellow TRPers. Having an issue at the moment with a recently promoted plate who keeps saying things and later it changes or "never happened". Classic gaslighting and I've already noticed she's used it twice now.

The first time was saying "hey do you want to go for a couple drinks with my sister and her boyfriend in a few weeks?" After agreeing, it later turns out that it's actually her mum/dad, cousin and aunt. Oh and there's also dinner involved. According to her this was all explained. I wasn't 100% sure though, as it was a few weeks prior.. and that is how gaslighting works.

This time though there's no doubt. She told me some information two days ago (the conversation is crystal clear in my memory) and today, not only is she denying she said it, she is denying all knowledge that the conversation even took place.

I really don't understand what the motivation is, because the information she claims not to have knowledge of is meaningless. It was a conversation about something that happened between two other people. Lying about it now serves no purpose, which is just serving to annoy me even more.

How do you think gaslighting should be handled? It's hard to confront it directly due to the nature of it and I end up looking paranoid to the shared friends we have.
