so ive noticed lately that my whole life my brother has overstepped my boundaries so many times and im sitting here nauseous and uncomfortable because he did it again so my brother has been touchy whole day and I told him multiple times to stop because at this point we've been out for the whole day and I just wanted to get home but he never stopped it feels like my "no's" mean absolutely nothing to him and it makes me scared to think about he kept constantly kissing my arm and pulling my shirt sleeves up even when I told him to stop touching me even up to a point where I shouted at him because I was disgusted to be in my skin at that point because I hate being kissed or touched by someone who isnt my lover or my mother. As im typing this im getting uncomfortable all over again. So please help on what I should do and if im being dramatic call me out.
