<human>: I've been with my boyfriend for a year and a half now and I think it's going really well. We moved in together recently and it's wonderful!

Here's the thing. We were drinking together one night and talking about our pasts or whatever and he mentioned his step father. He had previously told me the his step father abused him until he left the house at 17 but he wasn't too specific about what he did and I always assumed it was "normal" abuse like yelling/hitting etc.

Well it turns out that he did that and a lot worse. My boyfriend told me that the step dad used to rape him and would often times film himself doing so. I almost puked when he told me this but I tried to keep my composure and listen in a calm manner because I didn't want to upset him further (he was about to cry while saying this). We talked a bit about what happened (he went into horrible detail) and then changed the subject eventually. 

Ever since then I can't stop getting images of that happening to him. It will happen at work, when I'm relaxing with friends, having sex with him or whenever and it makes me want to cry every time. I don't think he remembers telling me and I don't want to bring it up to him. But I know that he knows something's up, it's so hard to hide my emotions in this situation. I honestly think I was the first person he told too and I really want him to get therapy or something because I feel like I need therapy just hearing about it.

To be honest...I don't even know what advice I'm looking for. I just want to feel normal around him again, I don't want to feel like I could hurt him with a glance or just feel so fucking sad and sick everyday when those images pop into my head. If anyone has some insight or perspective I'd love to hear it, but mostly I'm just venting out my sadness. Thanks for reading.

Condense the text into a few key points
<bot>: My boyfriend drunkenly confessed that he was a victim of severe sexual abuse when he was younger and I can't get it off my mind. Anyway to come to peace with this?
