At Christmas, 2021, my brother separated from his then wife. A few months later, he was in a relationship with another woman which seemed to be moving very quickly.
Then at Christmas 2022, he fell out with me and hasn't spoken to me since. This is because whilst I bought his children Christmas presents, I did not buy anything for her children. This is just because I don't actually know her children- I met them once for an hour and I had only met her twice. We weren't spending Christmas with them either, had we have been all together for the day, of course I would have bought her children gifts.
I am shocked out how quickly the relationship between them has evolved and didn't think that there would be expectations for me to treat her children the same way as my nephews so soon.
My brother then didn't deliver the gifts he had bought my own children for Christmas (his nephews) based on me not buying anything for his new girlfriend's kids. Seemingly, punishing my children. My children are slightly older than his (10 and 7) and noticed that Uncle Walnuttie had not bought them gifts for Christmas and I had to make up an excuse.I was shocked by his behaviour. I understand that his girlfriend means a lot to him and so do her children, but I don't/didn't know them. I thought the relationship would evolve more before we all became one wider happy family. I think I was also still coming to terms with him leaving his wife. His new girlfriend is lovely, absolutely no offence from me whatsoever, I just didn't realise that the expectations of me had moved so quickly.
My brother and I haven't spoken since. It just seems crazy.
Was I in the wrong for not buying her children gifts?
