History is shaped by our hands.

I may just be over-reacting. I was once before, but now I'm not so sure.
I haven't spoken to my gf in 3 days. She hasn't returned my e-mails. She's had computer issues before, but she would just call then. But then I checked and I realized that she hasn't called me in over 4 weeks. All of our phone conversations since then have been instigated by me. Except for one... she called one morning to tell me she was running late. That's it. She's home from school right now; the call is free. Its not like its costing her any money to call me.
And our most recent departure was kind of awkward. We had "sorta plans" to spend the evening together. But that afternoon she said she wanted to go have dinner with her family, because they were all going to be together for a change. I don't have a problem with that at all. However, it just seems odd that she'd break plans and then follow it up with 3 days of no contact.
I know all I had to do last night was call her, and then we'd talk and there would likely be an explanation, but I didn't feel it was my responsibility to call. As I stated, she hasn't called me in over 4 weeks. And even during that time, she's always returned e-mails, but there's no communication there either right now.
She has always told me that if there's ever anything that's bothering her, she'd tell me. She has said she will tell me how she feels, and is not afraid to tell me how she feels. If I don't hear anything bad from her, then things are fine. So, using that logic, everything should be fine. However, I don't follow that logic very well. When I don't hear from someone from days on end, I begin to worry that something isn't right, as opposed to just accepting that things are fine. If things were fine, wouldn't she want to talk to me? Wouldn't she want to hang out with me? We only have 10 days left before she heads back to school and we become a long-distance couple. Wouldn't you be spending time with your significant other in a situation like this? Or would you not communicate with them at all for 3 days because things are just fine?
After I got fed up with the State of the Union last night, I went right to bed. This was 2 or 3 hours earlier than I usually go to bed. I needed to escape my thoughts. I was worrying too much and it was driving me insane. I just wanted to sleep and let my mind rest. Then I had a dream, not necessarily a nightmare, but a very realistic dream about my parents that woke me up in the middle of the night; crying. I didn't want to go back to sleep. I didn't want to close my eyes, for fear of that dream starting back up again, and then eventually bringing me to tears again. All I wanted to do was lay in bed with my eyes open for the rest of the night. But that wasn't any good, because it wasn't long at all before the thoughts I had tried to escape by sleeping came rushing back into my mind.
I didn't want to be awake... I didn't want to be asleep. What was left?
I went to work in the middle of the night. Its the only place I can go where I can usually escape my thoughts and just concentrate on something else. Yet, here I am, blogging all those thoughts. There's no escape.
So what am I to do? Do I call her tonight? I would give anything just to hear her voice again. However, that doesn't come close to quelling my worries about her never calling me. I want to sit and wait for her to communicate with me... it will help me see that things are just fine and I'm over-reacting again. But its been 3 days, and all I want to do is hear her voice.
