Most Helpful Guy
What a bitch. Yes, she lied to you dude. Fuck that "friends" stuff. You really want to know why they want to be friends? Because they're selfish. They want to keep that emotional connection but without having to be committed. It's called having their cake and eating it too.
If you were really her friend then why would she feel the need to keep secrets from you? She's obviously defensive about it and she probably feels guilty too. You're a decent looking dude. Just forget about her and move on. Ignore her.
