I changed the title to avoid going too much off topic to explain words.
Sometimes, people keep denying having said or done something even though you know it to be true. They don't seem to be able to own up to their words/actions. It messes with your mind. Perhaps it can happen once or twice that you truly forgot you did/said something, but if it is a frequent occurrence, it's highly likely the person denying it is aware that you're right. Still, they refuse to admit it.
It's toxic behaviour. Most normal people (don't know if I should include myself there, as I'm not neurotypical, lol, but admittedly for this, it does apply to me too) would start to doubt their own claims. In my case, go check (if possible) if it really is/was true. If not possible, it still remains a doubt in the back of my mind. Something to be uneasy about.
If done often enough, you start doubting everything. Should I do/say this, or what reaction would come if I...? It makes you insecure. Insecure about things you shouldn't even think twice about. It messes up your life.
I wonder why people do it. Sometimes, I really can't for the love of God find any reason to lie about something. I mean, if someone messed up, perhaps they're too insecure to admit it. But even so, you would think they know that their denial isn't believable.
Even worse is when they aren't denying past words/actions, but claiming you did/said stuff you didn't do/say. They're now not even "forgetting" stuff but creating their own story. Making you feel as if you need to apologize, for stuff you didn't even do.
Again, it messes with your head. It makes you feel bad for something happening "to them, by you" that you didn't do. It's toxic behaviour.
How come some people aren't affected by this? I don't know. I wonder. I guess some of us are stronger than others.
Anyone who reads this, I hope you never have to go through something like that. Stay safe. Stay out of situations like that. Or if you're in, get out.
