My husband and I live a comfortable lifestyle, wanting for nothing but certainly don't have an endless pit of money. For context, we bring in about 180k as a household per year. I am a low earner personally as I work part time around my toddler which is perfect and I really love the balance I have. This being said, psychologically that is all I earn so I spend day-to-day as though that's all I have if that makes sense.
My brother and I grew up close in age and have remained close despite living in different parts of the country (he up north and we are London). He worked incredibly hard at school and uni, achieving top of class in everything he did which is amazing, and he is now a director at an investment bank and earns a huge amount of money.
Just recently the gap between our lifestyles feels like it's getting really big, and he often says things that I feel put me / my family down a bit. Example, he will text me things like "what is it like to fly in economy" as though he's never flown economy despite the fact he obviously has and I feel like it's him looking down on me. For context we fly all classes but we are sensible and won't spend on business unless there's a deal. He also says things like "I spend so much money, my credit card bill is £10k this month" and I'm not sure if that's him being braggy but I never know how to respond to it and it makes me feel awkward because I can't relate.
It makes me feel really bad and like he thinks we have nothing which I know is irrational and not true. I'm just looking for people with similar experiences and how to manage them? I don't want to say anything because I don't want to draw attention to it with him. I don't want to say anything to my husband who works hard for the life we have and I am grateful that affords me choices. My relationship with my brother is important to me, but I don't know how to navigate.
Help/advice/similar experiences please x
