<human>: I'm a 23 yr old male and I've been dating a great girl since April and she left for Southern Cali for the summer in mid-June.  We've been texting, calling and even sending some care packages back and forth.  About two weeks ago was the last time we talked.  I've called a couple times and sent a couple texts since then but no response.

Now I'm not a jealous person or a boyfriend that needs constant updates but this is a change from normal and I don't now how to proceed.  I've just been trying to wait it out and see what happens but I've got this persistent voice in the back of my mind that is bringing all my fears and doubts to the surface which doesn't make waiting any easier.  

If I'm being a crazy person, let me know but I feel like I'm being reasonable.

Should I just keep waiting and see what happens or should I attempt to see why she hasn't been getting back to me?   I don't want to seem clingy or anything but I also don't want to spend my summer pining for a girl who is ignoring me.  What do you think?

Condense the text into a few key points
<bot>: Haven't heard from my long distance gf in a couple weeks after fairly consistent communication.  Trying to figure out my next move.  Doing my best not to do something stupid.
