If a child cries for help, saying they're getting abused, and then later retracts what they said by telling everyone something like "I was just overreacting, they're my parents, we fight all the time..." or something along those lines, ur first instinct should be to not buy it.
If they do this it means the child was most likely gaslit. It's a common tactic by abusers especially covert narcissists. They tell them over and over again "i didn't abuse you, you're making this all up in your head, we're your parents and we love you so much" etc
The abuser will always try to convince everyone else around them, including the victim, that this is normal. Like, "we fight all the time like any other mother and child." Or, "i just have anger issues i need to deal with." And they are very manipulative so it works.
A lot of the times, the child retracts their statements because they're scared of what will happen to them if their parents get in trouble. Because covert narcissistic parents make their children extremely dependent on them and thats how the manipulation is so powerful.
An example from my own life. This was right after he tried to convince me there were security cameras installed in the kitchen watching me binge. They always pretend that they love u and manipulate the shit out of u like this.
