<human>: Condense the text into a few key points

A little background info: we both live in the same dorm, so I will likely see her at least once a week for the next year and a half, excusing breaks.

I was never given a chance to say anything, so I feel like there's room for confusion here (what if she thinks I was seeing this girl on the side? Which is in no way the case) We haven't spoken since; her words were "if you ever speak to me again…", pretty clear and concise. I feel horrible. Horrible doesn't even begin to describe it. I can't ever forgive myself or blame her for not wanting to speak to me again. But I also feel obligated to try to make amends somehow. Unless I really should just never speak to her again, how should I go about this?
<bot>: girlfriend broke up with me because I had less than appropriate pictures of another girl on my phone, haven't spoken since with no input on my behalf, what now?
