Yes I had it with both parents, and then with an ex.
They tell you that certain memories didn't happen, sometimes they twist it around but other times it's complete denial.
Also if you tell someone how you feel and why you feel that way.... gaslighting is when they try to tell you you feel a different way or you feel it because of a different reason.
A clue that you are being gaslighted is when you know you are explaining yourself clearly yet you keep having to go over and over it trying to explain it in different ways to be understood.......makes you feel like you are incredibly complex and impossible to understand, your thoughts are weird and there must be something wrong with you.
But really you were calling out some very obviously bad behaviour, and stating the appropriate corresponding feeling that you felt.
Another major clue is when you KNOW that something happened, the other person denies it happened that way or at all...so you find yourself looking for evidence that it happened to show it to them to prove that what you're saying it's true...whether that's screenshotting things they said to you, googling dates and times, any evidence at all that proves that what you are saying is true because the person point blank refuses to acknowledge it.
It's all round maddening behaviour that leaves you in a constant cycle of explaining yourself, defending yourself, explaining why a behaviour was wrong, explaining why your feelings are appropriate, feeling right but then wondering if you're crazy because you must be because they deny everything.
