Does anyone else crave an older brother or is it just me being weird?

So I never had an older brother to grow up with, not even any cousin. And more than wanting a boyfriend, I find myself craving for an older brother who in my head is this really nice guy with whom I actually have a good relationship with. I want that brotherly love and safety where I can fall apart in his arms without judgement and he will be that space where I can cry into. And anytime I want some life advice, I can go to him. And I can really look upto him and trust him and we can have a close relation. I want the funny banter and the platonic affection of an older brother. And idk if that's weird cause from what I have heard, these are supposed to be the expectations you have from your partner or ur boyfriend. So is it weird that I have this image of an older brother in my head?
