OK, so I live with my brother in the US. We're both international students, he's in high school and im in college. We have been living together for the last 3 years and now he has graduated. My brother who I will dub C and I have not really gotten along over the last 3 years. We initially started the first week on good terms, but then after our grandmother came the week after things started to go haywire. Every year, it feels like things have been getting worse, to the point now that my brother is indirectly making my life difficult through our parents harrassment. I'll give you an example, using the recent incident.
Ok so I'm a frequent potsmoker, so I sometimes have weed in my room, like I did on this particular day. My brother was supposed to give me money that had been sent to him and he did(only putting half in my room sending a pic as proof, saying thats all he could get at the time). A few minutes later, I get a message from my mom showing a different picture in my room, but of the weed in it. My brother had taken a picture of it sent it to my parents and used it as a cover to hide the fact that he didnt have the remainder and then also was going out very late from my parents. U till now both of my parents have been hounding me about smoking habit(which they do not like, but I usually manage to keep hidden when they visit), when they never would have in the first place if my brother hadn't done what he did.(because they are in our home country). Thats what pissing me off right now.
The worst part is that when I confronted my brother about this, he literally admitted to all of what I suspected, and when I tried to ask why he is doing all of this, he told me "Don't you know? I think you are a bitch, a pathetic kid. Don't call me, text me, ask me for food, or anything. I'm done."
I don't know what to do, but clearly he wants to cut ties with me. I dont really want to but not knowing I have my sibling, even in spirit is a stressful thing to think about. I don't really want to have things turn out this way, but whatever. Maybe time will tell him that he will need me, because whether either of us like it or not, we are stuck together. I just wish he could understand that. Does anyone here have ties cut with a sibling or family member? I would love to hear how othes coped like this.

Sincerely,
Broken Onii-Chan

i dont have any cut ties in my family but my younger brother has a very strained relationship with everyone but me in my family and its only fairly recent that we started talking again, but when my brother cut ties i was persistent not to lose him it took time, most of which i felt that it was hopeless and that he would disappear, but i eventually got through to him, things with the rest of the family are unstable at best regarding him but we act like we use to

the point is everyone has rough patches in life and even though its sometimes better to let go you shouldnt, family is all you have at the end of the day and maybe in a few years or so he'll realise that.

maybe he feels the way he does because the younger brothers tend to look up to the older ones and he feels that you dont qualify or maybe he has his own problems that he cant talk about and feels the need to push attention away from himself towards someone else what ever the case i hope you reconcile some day
