My brother had a girlfriend who was insane and I warned him about her, but he didn’t listen

My older brother had a relationship with a girl who was very insane. She cheated on him with his best friend. She was part of the reason why he lost a job. However there was more than that. He had told me that she was crazy at first but that he seemed to have changed her. That statement was a lie because she gave him chlamydia and had scabies and yet he forgave her for all of these things. He even gave her a car that my grandfather bought for him and yet he gave it to her upon leaving him. He neglected his own family for her and yet he was shocked when she left him for one of his best friends. He had been so far in his own delusions that he ignored my warnings of her.…<br><br>He wishes he never met her and that he had listened to my concerns. <br><br>If I ever met her I would spit in her face and tell her to go fuck herself.
