<p>if she calls you “brother” then that just tells you she’s not interested in you that way. Any person who refers to the opposite sex as a sibling indicates that they like you the way they love/like their family members. It’s just the way it is. –>
“I’m younger than her, she calls me her brother, and we’re just really close friends.”</p>
<p>And how exactly do you describe “relationship stuff” for example–>
“So here’s another complication to all of this. Our friendship is kind of an odd one…we sort of act like we’re in a relationship even though we aren’t and even though she doesn’t like me. Like we do a lot of relationship like stuff. I don’t know what to make of that.”</p>
<p>and fyi if the girl isn’t interested in you and you decide to tell her your feelings… the friendship after your confession will become awkward; that is, unless your friendship is strong enough to survive such a confession.</p>
