MY ex sister in law wants to know why my brother acts like this... here's the story... One minute he's telling her he loves her, the next minute its "Fuck you bitch" literally! When she finally decides she's had enough, she will tell him to leave her alone. she's been going through this bipolar shit for five years! he's cheated on her too many times to count. When she tells him to stop texting her and leave her alone he's all like "Baby I love you please talk to me" "Why do you gotta be that way?" blah blah. she's so hurt. YES my brother is Bipolar and Narcissistic REALLY BAD. She says when they have sex all he talks about is how big his dick is and asks her how bad she wants it. he's SO FULL OF HIMSELF! HE also gets so pissed off if she won't have sex with him. there's so much more I could say but I dont have time to say it all lol. I mean all my brother does is talk about himself. HE brags constantly about how much money he makes on facebook. He even takes pictures of his money and posts it on facebook. HE takes stories of other peoples lives and makes it his own. Whatever he likes about someone elses life, he will turn it around and make it seem like its his life. Like say for instance. If my step dad had owned 3 harley motorcycles in his life time and was in a bike gang, My brother will say HE owned 3 harleys and was in a bike gang... LOL at least thats what he will tell a woman to try to impress her. MY brother also likes to start arguments and stupid shit because he thinks thats all part of a 'healthy relationship' He was dating a sweet woman once and would start arguments with her and yell at her because he thinks its 'healthy'. PLEASE TELL ME WHAT IS WRONG WITH HIM!!! My ex sister in law wants to know whether she should stay or leave. They do have a little girl together. she's very conflicted and heartbroken.
