I don't know enough about this to answer this question. If you hurt her she may not talk to you for a long time. If she is just now being cold she may talk to you when better. Meh women make me nervous
well, no one stops talking to one another for no reason so tell what you did wrong and i give you my solid advise and i wont judge you.
Blank her. she doesn't deserve your attention after the way she treated you. She should have told you why she is not speaking to you anymore but she didn't. Not cool.
Space, dude. You gots to give her space.
Just move on.
If she wants to talk to you,she knows where to reach you, i'm guessing.
It's hard to say.
It depends how you know her or met her. If she's a friend local to you, maybe you can meet for coffee, write her a letter or send her a email/message, say that you miss hearing from her and see what happens.
If she's an online friend, then try an email or message, see what happens. From personal experience, some people online can vanish with no explanation and there isn't much you can do
If talking to Her doesn't lead to her answering you, just give up on it. It's not worth putting all of your energy into one person when they do not like you that way.
Never give up hoping. You never know.
