She might have a boy, in which case you’ll be an uncle

(joking)

Aunts are a huge deal in a relationship, as an aunt is like a best friend to a niece or Nephew

My aunt was like a second mother when I was younger, I basically spent nearly all my summers with her until I was in my mid-teens.

Aunts and or uncles can play a huge and important role in a child’s life . They can be that child’s friend . Be the one that they ask for advice.
I have hung out and gone to movies with my aunt.
