I noticed some girls will support the toxicity of a fkboy who ill-treated her while i am trying to talk sense to her that what the guy did to her is wrong. What should be the correct way to talk sense to her?

I'm a guy so i will definitely talk 'logic' to these girls by default. i myself dont like to be stuck dwelling or ruminating so i had my own set of coping mechanisms i do to move on from fked up ppl's treatments. i realised whatever i say dont work so i cut the first girl off since i dont like to waste my time n effort on ppl beyond helping. 2nd girl still very early in the stage of realising she got played. its her first experience w a guy n she kena a fkboy who used her n then bounced. i asked ai n it said to just listen, empathise n validate. i sort of cant do that cuz i know that she will start ruminating the good things that happened between them n what could have been even thought she got used n played in the end. i know that the stupid human brain will keep looping the memories pointlessly to find answers or conclusions. so my default thing to do is to try to snap her out of it by telling her truths n trying to change her sadness to anger at the guy instead. i know we have all our different kinds of coping mechanisms, some healthy n some unhealthy. i do not want her to become the type that will go down the unhealthy coping mechanism way n then spiral even further (e.g. going back to him or finding rebounds back to back or finding more toxic guys) to cope. i did tell her that her sadness is valid.

what method works for u guys n girls when talking to a female fren in these kind of situations?
