Paranoid or Legit?

I’ve been dating this girl for over 6 months. I think I love her, but there are a few red flags that have been bugging me. 1. She either acts like we are more than friends, or she ascots like she doesn’t like me at all, not even as friends. “Hot and Cold” by Katy Perry fits. 2. It’s the summer so we don’t see each other at school, but she never responds to my texts though I get read receipts. 3. She acts weird when we’re around her family. I mean we are in a queer relationship, but me and her brother get along well.

Am I just being paranoid? Or is something wrong?
