I’m really sorry you don’t have the sibling relationship you really want with your brother. I can relate to an extent - I’d like to be closer to my brother, too, but while we do get along, it’s pretty much surface level, casual and I don’t see that changing, either. Guilting your brother won’t get you what you want, and even if it did result in him communicating more, it likely wouldn’t make you feel better because it wouldn’t be authentic; for that, you’d both need to show up because you want to, not out of guilt or obligation.
Do you like your brother as a person? Is he someone you’d want to be friends with under other circumstances?
Not saying this is your case, but a lot of people make the mistake of thinking family = people you have to get on with, and feel guilty/sad when they don’t. Rive’s suggestion about direct communication was good. You would know where you stand, at least.
