1. She doesn’t kiss you when there is an opportunity to kiss. For instance, you move in for a kiss and she turns her head so you end up kissing her cheek.
2. She declines your offer to walk her home, walk her to her car, etc. She wants to avoid the awkward moment of being alone together and the potential that you’ll make a move and she’ll have to turn you down.
3. She ever says that you’re “like a brother.”
