<human>: I moved 2200 miles to live with my girlfriend of a year, and we've been living together for 4 months. She made it pretty clear to me that she wouldn't want me masturbating to porn once I came. This was something I was VERY used to doing back home being single, and it's been difficult to curb the habit since I've been here. For the 4 months that I've been here, she has caught me twice, and both times she told me that she wanted me to leave because of it, and that she feels that masturbating to porn is the SAME as cheating. I promised on everything this last time she caught me that I would never masturbate to porn in our home again.

About 5 minutes ago she caught me masturbating after she left for work and came back home for a moment (I was leaving for work in an hour or so), and she told me to pack my shit and leave. What can I do to make her understand that it's very difficult for me to stop masturbating to porn because of how used to it I am, especially when we haven't had sex in a while? I do acknowledge that I am completely at fault for promising on everything and breaking that.

Can you condense the text into three sentences or less?
