She'll get your messages, so for now back off and wait till she contacts you. If she doesn't call, I hate to break it to you, but maybe she wasn't all that interested... Which, I know sucks, but there are other fish in the sea.

Wait till you get into long term relationship (you don't sound like someone who's been in one yet) and your GF starts asking for a break....

Good luck she is most likely playing hard to get and will probably call you back in a couple days.
