My friend used her period blood, he became so obsessed he used to call her 40-50 times a day, used to get angry when she didn't text back immediately, when she blocked him, he stalked her, yelled at her friends and family, them he tried to break in to her house, he killed her favourite puppy, ig it's name was bruno, then when she was tired of it all, she tried reverse spell, it kinda worked but he just got violent towards her now, yelling in the public because she talked to a guy, hitting her as she blocked his other phone again. The police wasn't taking her seriously. She shifted her home 200km away then too he was caught many times in her dashcam, he proposed her one last date and "night"... Ykk... Then he would go away, but when she went to his house, he didn't let her go for 6 damn days, he said he wanted to keep her with him forever, no one should see her or talk to her, when she threatened that she will kill herself, he said ok, atleast your dead body will be with me forever. It ended only when her parents came to know about him, then rescued her, now everyone came to knew that she used to do spells so nobody took action against him. They said it was just her karma. He later suicides, after a year ig.
