I know that this is not about boyfriend/girlfriend relationship, but this is about my family relationship with my little brother. On August 18, me and my sister blamed on my little brother (who is becoming a sophomore in high school next week) for hurting a baby name Jay that my mom had babysit a long time ago. My brother carried him, and Jay suddenly starts crying. Me and my sister overreact towards him and start blaming on him. He got mad after that and that's when he starts to avoid me and give us silent treatment. I did apologized to him 30 minutes later, but he is still mad. I tried to talked to him on Friday for reconciliation, but he won't listened to me and won't accept my apology. I tried my best to get my message towards him, including writing messages to say sorry and leave it on the table and even tried to texted him (I assumed that he purposely blocked my number), but I don't think he ever bothered to read it. My mom did talked to him, but he seems like he doesn't care. His attitude is becoming more and more ridiculous. He doesn't act like himself (being positive, funny, weird, and get a little upset). The next day, whenever we went to the store, he always finding a place to hide and try not to make eye contact and still avoiding us. My sister tried to approach him and said sorry, but he didn't listen and didn't even bulged. That's when I started to give him space and didn't talk to him since then. Yesterday and today, he seems like he is getting back to his normal self. He talked to my mom and dad pretty fine. But when I approached to him, I asked him if he wants to play Fortnite, he shook his head no and didn't say one word. I am heartbroken that he act this way and didn't want to forgive us. I didn't even have a clue of what bothers him and how can I make it up to him. I'm starting to feel concerned that one day, me and my brother will become strangers. I'm currently feeling stuck and I feel more depressed from time to time. What can I do to make him stop getting mad at me and try to move on with the past? Can you give me an advice on how to make him talk and listen? Thank you.
