I added girl on Facebook, but she doesn't talk to me, why?

I don't think she means to hurt your feelings, but some girls can get really freaked out by things like that. I'm not saying you freak people out, but that people can get a little creeped out at first, because it might be a bit of a shock to her, I'm sure she'll get over it. (I'm trying to explain this without insulting you, I'm so sorry if I upset you.)
Sometims when you're on the Facebook app, it says you're online and you're not, and when you go on the app, it says you've seen the message when you haven't. I'm sure she'll be talking to you again, it might not even be related to your condition, it could've been one of her friends on her Facebook account. And don't be nervous! if a girl doesn't like you for who you are, then she's not worth it! Be confident! You're obviously a lovely person I hope she talks to you soon x
