Chloe is a good friend, and you'd trust her almost no matter what. But you want to know more about why she's been acting weirdly around you
"Hey" You say to her "Hi" she almost squeaks out "I'm going to be blunt, but I wanna ask, why have you been acting different around me?" She scoots away on the couch a little bit before saying "I...Um....I don't really....Wanna talk about it, okay?" she manages to get out. "Chloe, we're friends, you can trust me with anything." You say to her, "I really don't want to talk about it." you try and ask her again, but she ignores you.
Welp, guess you do have two other people you can talk to.
