Please be kind! For background - sibling and I haven't been particularly close growing up. He moved to another country and has his life over there now... Wife, 3 kids. My parents love to visit and speak to him regularly. Because him and I weren't close growing up / neither of us great at keeping in touch. However I now have some growing bitterness about seeing his glorious, successful lifestyle on the family WhatsApp... All he does is share the rose tinted, amazing parts of his life (amazing house, amazing holidays, videos of my nieces doing things - they're very rich too, as he owns a successful company, but he doesn't seem to have an ounce of humility and will readily share all his new stuff etc). I wanted to leave the family WhatsApp as I'm fed up of it being a social media feed of his amazing life, but mum got upset when I said, so I muted it instead. I delete his posts as I can't bear to see them (yes I am aware that jealous probably comes in here and it is an ugly trait!) ... So to combat my ill-feelings I tried initiating positive contact more, to be proactive and try to grow some relationship, but he not his wife ever answers my video calls and never returns missed calls. He never visits our country anymore now he has kids as he says he never has time because of his work, and we can't afford to visit him (plus I don't know if I'd want to waste annual leave or money doing so, even if we could afford it!)
I feel like our relationship is over and I have no more emotional energy to invest. I also feel like I don't have a lot of love for my nieces as I don't know them. I struggle with anxiety, plus have a child with a disability, so life is draining and hard. My capacity feels empty.
My aibu - aibu to act as though I no longer have a brother and let our relationship fall into the zone of no contact? Even though I'm an aunt to his daughters? It just hurts and I feel like giving up. But I can't help but think family is family and maybe in the future we will need our blood-relationship?
