Prefacing this is about a year old incident, where a white women interacted with a male with darker skin colour, and their friendship escalated in a unfortunate direction. The male friend has a somewhat rough upbringing, in terms of grandparents weren't as nice, especially around holidays.

The woman had been friends with him for a few years at this point, but the woman noticed unusual behavioural signs that their friend displayed, and it continued for days. The male became more passive aggressive over time, as the woman became more worrying and inquisitive, the woman wanted to offer support. then one day, a storm hit out of nowhere (metaphor for verbal aggressive tone), the male kept saying harsh things towards the woman. the woman had to be calm and patient, but it persisted over a short time. the male kept insisting the woman was an enemy, and only staying with the male for superficial purposes. after that, the both stopped seeing each other for a while. About 2 months later, i see a notification on my phone from one of our mutual friends saying he got caught?? so the woman asked: what do you fucking mean he got caught?? tell me! The friend explained that after his aggressive and persisting behaviour with the woman, the male was seen clubbing and a few white trashy money flexing men looked at his direction and approached him. They said something agitating to him, and persisted with it until he threw a punch and crabbed the collar of the white trashy boys in the club. it escalated, (sorry for not elaborating, its too emotional still to share), and police got involved. A few days after, the woman was still trying to contact the male, but was refused. A few weeks passed, and the mutual friend updated the woman about how he had to experience psychotherapy, and was too unstable and projected it onto innocent people.

Thanks for listening to my experience. what could i have done?!? i am scared if another person i care about keeps showing these persisting and unusual behaviours, and if it escalates into something worse. Sorry, if my story is not appreciated, i just did not feel safe sharing it.
