It ended up that these girls would ask him for money, and he drained his savings accounts giving money to these “girls”, and even after running out of money, he kept believing these girls were real, they wanted to know him as a person, and that they just needed a little money to help out.
Everyone close to him, including his family, kept telling him these girls weren’t real, to stop contacting them. He would briefly relent, delete all his messaging apps these scammers were using to contact him, then he would feel lonely or what not, reinstall the apps, and resume contact with the scammers. It didn’t matter how many times we told him they weren’t real. It didn’t matter how much money he lost from these scammers pitching their wares to him.
He just stubbornly believed these were actual young girls who wanted to be his friend, no matter how many people told him they weren’t real, that he was just setting himself up to be scammed yet again.
I had to break contact with him. It just really angered me that this guy couldn’t believe something as basic as these girls actually being African/Southeast Asian/etc. scammers and not real people wanting to get to know him.
