Uh. Did you find out WHY she didn't answer.
If you broke up with her without even talking to her then you shouldn't be in relationships, because they aren't gonna' last. The number one key is communication. She was probably busy and forgot, who cares? It's not that big of a deal. Don't be so pushy.

You have probably just shown yourself to be a tool.
You over-reacted in a big way.
It was possible that she did not respond because she did not have a functional telephone, or there might have been a problem transferring her contact list to the new telephone. Or any one of a list of other possible problems.
You did her a favour, I think. A smart girl who had self respect would move on immediately.
