My brother proposed to his gf last week, who I love and get on really well with, and I am so excited they are getting married! I am quite close with him but know obviously he was not obliged to tell me of his plans to propose. He didnt tell our mum though either. Its just him me and my mum so not a huge family. However he proposed in a restaurant in front of all her family and they knew beforehand & bought banners and gifts. AIBU to be a bit upset that we couldnt share in that moment with them too or at least had an idea of his plans?
