<human>: I (M21) have just began a long distance relationship with my girlfriend (F20) of 7 months for the first time. It started off fine but lately things have taken a turn for the worse. My girlfriend thinks if I don't drop all the plans I have for her, that means I don't care. We had initially agreed to talk on the phone three times a week, but that went out the window. 

She got upset with me last week because I would not leave lunch with an friend to call her after a bad test. I was texting her for an hour, but eventually told my friend I had to leave just to talk to her. And when we talk she expects to talk for hours, even when I've told her I'd like to know beforehand. When I have to go she gets upset if I leave and she isn't happy. 

I would love be available for her whenever, and be able to cheer her up any time but the distance makes it very difficult. She thinks it's unfair and unreasonable that I sometimes put my own plans ahead of talking to her. I don't know what to think. Am I being a jerk?

Provide a brief overview of the text.
<bot>: Newly long distance, my gf thinks I'm being unreasonable by not being able to talk to her at any time.
