Ok, this girl name Rachel we used to get along a long time ago, then she found how I really am, then she started being rude to me, and send me stupid messages on facebook, after that we started making deal with each other, by talking on facebook, then she blocked me. A day later she unblocked me and sent me a message. A few months later she started messing with me. I sent her a message she just responded with some kind of weird code, and said “??” Then she said BYE. after that she blocked me again! I got this dude to message her for me, before I found out to message a blocked person with a little magic, she unblocked me again then sent me cuss words, and mess with me, after that she blocked me again!! Last night I tried to message her I know she blocked me. But I know her email address, I hit send a new message, type in her email. I sent her that messages and it worked!! It showed her full name, but no picture. I didn't receive a mailer daemon message at all!! But is she going to reply though? Is she going to ignore it or delete them? Please help!! She likes to mess with me at school and smile at me. Just how can I find out if she ignores my message? I can still message her, but I can't see her profile to see her recent activity! Please answer?
I need to know, because I will never know if she's busy, doing something else, or having issues with her computer!
