Just to give some background, my brother never organises anything for my parents I organise everything, presents wise from start to finish, with not so much of a thank you and on occasions I even pay for his half of the gift. I should make it clear he has a v well paying job so money is not the issue for him. In December I organised our parents birthday and Christmas presents and even organised to buy his new gf (of 12 weeks) a little £30 present. Come Xmas day, he hadn’t bothered to get my finance a present at all. Which really upset me at the time.
Now on a weekend that I’ve had in the diary for me and my mum to do my wedding dress shopping for the weekend he decides it’s the weekend my parents can finally meet his new gf so all plans have now changed to go for dinner with them. AIBU for being incredibly upset by all of this?
