<human>: My girlfriend lives in Germany and I'm in the United States. We lived together every day since Christmas until April. Sex was slipping and I began not to initiate because I became un-attracted to seeing her all the time and took her for granted being there. I wanted something crazy.

The first time she flew back to Germany I cheated on her a week later. It's two weeks since she's back home and I want someone. It hurts not having her here. She's my best friend but I want some thing new physically.

I've told her I want an open relationship but she says she will not. I'm not seeing her from April until August. I hate using Skype.

I don't want to cheat on her again but I think about it every day and it gets my blood pumping and turns me on.

Can you condense the text into a few key points?
<bot>: In a long distance relationship - USA to Europe. Not seeing girlfriend for four months and I told her I want an open relationship. She said it's not possible. I don't want to cheat again.
