Girlfriend troubles :/?

hey, well i went on msn last night to talk to my gf and she did not reply back to me so i dint think much to it at first but then she hasn't put on her myspace or face that shes loves me and shes gone kinda of emo because she usely puts Jess <3 jack <3 but now nothing and shes has a very emo message on her myspace status so im not sure what this all means... so i said to her on msn hey are we still together right? and she said ye what made you think that and then i said about the myspace status and all of that and she dint say much, i think i worry to much and the fact that she is my first ever girlfriend doesn't really help... by the way this happend last night so i hope this whole thing could of blown off by now who knows. girls ay
