They've been there through a lot. You don't hide shit from them. Even if they don't want to know about anything you have to say.
You've gotten close, that magical close where you dont "want" them, but you "need" them.
You have thoughts though. "What if I'm actually annoying them?"
"Should I just back off?"
"NOPE. They will endure my presence. Whether they like it or not!"
They are like family, their parents love you and you treat their brothers or sisters like your own."
This is your best friend. You will never find another person like them. Ever.
