<human>: A sexual assault happened on our college campus by one of his fraternity brothers.  The brother in question took a picture of the act and posted it to their fb wall.  My boyfriend took a screenshot of it and sent it to me.  I was horrified so I sent it to my friend who is in the sorority of the victim after she told me she'd heard there was a photo and had seen an anonymous post on Yik Yak (hard to explain) about it and now the brother is being investigated by the school for sexual assault (rightly) and being kicked out of the frat (rightly). 

When my friend asked me who took the screenshot, I truthfully told her it was my boyfriend. Now my boyfriend is afraid that his fraternity brother, who is extremely violent and absolutely crazy, is going to hurt him somehow and he is furious with me. He feels that I threw him under the bus (if I did, it was unintentional).  To add a little context, this isn't the first time he's felt that I've "thrown him under the bus"  but this situation is very different from the others.

I don't know what to do. I've apologized over and over and he replies that he's too stressed for the apologies to even register.  He won't look at me or touch me.  I love him so much and it is destroying me.

Summarize the given text in a few sentences.
<bot>: I told someone that he (truthfully) took a screenshot of a photo of sexual assault and he won't look at me or even acknowledge my frequent apologies.  How do I fix this?  How do I proceed?
