What's Going On With Her?? Did She Meet Someone Else?

Well we've been talkin for about 5 months now. We met through myspace and everything started off real good. We would text, talk on the phone for like the entire day. Then she began to change she went through something really tough in someone's life and I tried to understand her. She would still be loveable yet, not as much. She said that the past experience she went through changed her and kouldn't be the same anymore. Then again we had a konversation and well supposedly everything went back to normal for like 1 or 2 days. After that which was this past thursday she didn't call me that one night neither did she text me at all. Its usually her the one who calls me and if she's textin me konstantly I call her. We do this because she is a very busy person and I try not to annoy her so she kalls me and I text her. Bottom line is that she hasn't called me for like 4 days now and yesterday we talked but for like 1 minute. She don't text me as constantly and takes really long to answer back but then tries to kall me "kute" names as if everything was ok. What's going on??
