My brother ignored me for no reason when I was in public, now I feel too heartbroken? Should you only trust yourself and no one other?

He sees you all the time. I would have no need to acknowledge you either !! Especially, if I am working on a female...

so, decisions (nor my assumptions) should be based on just one incident
