I(16f) have a little brother(14m). For a little backstory we grew up very close, sharing a room for like most of our lives until I turned 12. A couple of years ago when we moved into a new house my brother developed a nasty attitude and a habit of lying about stupid stuff just to impress people. I think he's a pathological liar. Half the stuff he lies about it's for no reason, he just says it and then runs with it. These last couple years have really been messing with me. First of all, when i went to highschool, he was in 7th grade. By then he was already lying to his ENTIRE class telling everyone who would listen that he's being "abused" at home, and that he had to get a job at the ripe old age of 12 because he wasn't being fed at home. I got dozens of texts from his friends asking me if I was okay. Of course I was okay. We grew up upper middle class, we never went to bed hungry, he got every single thing he ever asked our parents for. When I confronted him he just yelled at me and told me that I'm just angry because I'm, in his words, "fat and bored". Yes, I'm a little plus sized, but this was out of nowhere. I just asked him if he was okay and why he was telling people that he was being abused. Maybe I could've worded it nicer? Anyway, more recently, he joined my highschool and immediately started tormenting me. He would tell all of his friends that I "stalk people" and making up other ridiculous rumors about me just to piss me off. In the halls if we passed he would laugh and point at me for his friends. If these friends came over to out house and I DARED to go to the kitchen he would yell at me and tell me to "stop eating before I explode." Infront of everyone. He does it on purpose, i think it makes him feel better about himself when everyone else feels like shit. Today though he really struck a cord. We have tutoring together every week but this week we had a full 2 hours at the same time. Usually we have an hour together but at different tables, and then he woukd have an house before I got there, and I would have an house after he leaves. I was trying to do my work and he was bothering me on purpose. He would put his hand on my workbook, poke at me, snicker and then look away if I looked up. After the first hour, I was pissed, but luckily he was moved to another table. At this table he proceeded to yell and tell everyone how he "made $800 but taxes left him with $300." I immediately knew this was bullshit, as taxes are not that high and hes 14, so he can't even work where we live. But I stayed quiet because it was none of my business. His tutor then turns to me and asked me if this is true. I think she also thought it was unbelievable. This might be where I'm the asshole. I told the tutor "no. It's 14. He's lying." After this he started yelling at me and distrusting everyone else trying to learn. His tutor told him to quiet down and instead he just started making up fake embarrassing stories about me. He said that I cried in class, that I broke a scale, I'm failing all the classes and so so much more. I honestly just ignored him and kept working and then in the car on the way home he was full on screaming at me for embarrassing him infront of the whole table. There were 3 other people there, including the tutor. The whole car ride home he would scream about how I'm useless in this world and how it would be better off without me. AITA? I think i could've just not answered and avoided all this, but he had it coming a little after all this time. Let me know any questions and I can clarify :)
