PLEASE, girls answer - i was in lov with girl on chat, but then ...?

Well, if it happened relatively recently, right now she's probably a bit scared, because she thought she could trust you and then something like this happened. If she's blocked you there's not much you can do about it just now, but give her some time to cool off. She's probably thinking that she feels betrayed by you right now, because she thinks you were nice to her and then sent her those horrible messages, even though you didn't. If you really love her, what you need to do is let her have some time to think over what happened. If that doesn't work and she's still blocked you, use another screen name to contact her. Send her one long IM that tells her exactly what happened, and then see what she has to say. If she says that she's still freaked out and doesn't want to talk to you, leave her be. It will only freak her out more if you keep talking to her.
