My younger brother and I never got along well. He has had a pretty difficult childhood because of my agressive father and has been verbally and fysically agressive towards me on multiple occasions in the past. Years ago I went to visit my uncle in a country in Latin America from where a lot of drugs is coming into Europe. My uncle is not involved in this business at all, he has a local business in tourism. My brother had been there shortly before my visit and suddenly texted me to tell me that he had left his jacket there and some other clothing and he basically demanded I take it back home with me for him. My mother told me years before that, that my brother used (hard)drugs sometimes, he’s never been an addict afaik but she found some in his pockets when she did his laundry. Because of this I immediately felt uncomfortable about his request and told him I’ll probably have no space in my suitcase to bring back his things. He was then becoming increasingly rude and pressuring me until I pretended to give in, thinking to myself I would pretend to have forgotten it at my uncles house and just leave it there. The first time I saw him after I came back without his stuff, he was incredibly rude and picked a fight with me. This has been ages ago and we have hardly spoken ever since. I’m wondering these days if I have been too paranoid towards him that time he asked me for a favor, should I apologize after all this time about this or did I make the right decision at that time? I grew up in a very dysfunctional household and I have a lot of issues with poor boundaries. That time I asserted them because I genuinely felt uncomfortable.
