<human>: Can you provide a brief overview of the text?

So me and my boyfriend(ill call him James) went to this party. It was pretty big, there were plenty of old high school people we used to know. We met up with them and it was cool, everyone had a good time.

One of them was a guy i hooked up quite alot(ill call him Christian, hes 23), he was a bit of a player. I think even after all these years we still have a bit of chemistry, but ofc im loyal and wont ever cheat on James. 

Anyways, throughout the night Christian was just taking so many shots and got really drunk. He was stumbling across James, and said "you know, shes a really crazy one in the sack". James was trying to play it off, and then Christian was like "no, for real, ill show you." then he took out his phone and showed an old video of us having sex.

Not just any kind, it was really screwed up. Im actually jewish and hes german, and the vid was 5 minutes of me in a concentration camp costume and him in a nazi officer costume. i mean i liked roleplay alot but i never really did it with my bf James. And it was me being so degraded, like him telling me to take it like the slut i am, then at the end it was him cumming on my face, all sorts of embarrassing stuff. 

James then got really mad and asked me if that really happened. i was so embarrassed and in tears at that point, but i couldnt really deny it. Christian then said with a huge smirk "what did i tell ya?". James then grabbed him and said "you wanna fight"? 

I tried to get him to back off. He eventually did, then said to me, "you know, thats really sick, i cant believe you would do stuff like that". then he left the party. It was last weekend and he hasnt been texting me since, ive tried texting him how much i love him and everything. What should i do?
<bot>: Old high school friend showed boyfriend a video of really weird sex, nazi roleplay. Boyfriend got really mad and is now ignoring me?
