I was telling my friend about a boy I was talking to and she was asking about him but I didn't wanna say anything so since I wasn't answering her she got up and asked some other girls at the other lunch table.

When I was gonna ask her if I could talk to her in the hallway she started saying no until I tell her.

I told her I can't trust her since she got up and asked the other girls about it and she got upset with me for saying that. She even said she'll investigate about him so she'll know.

Whenever I don't tell her something she tries to say she's my friend so I should tell her everything, but just because she's my friend doesn't mean I'm gonna tell her everything especially if she's gonna ask someone else.
