Boyfriend showed people our sex tape

So my partner is a miner and works away 2 weeks of the month. After about two years I’ve built up enough trust to film some saucy videos with him. The one in question is me naked giving him oral to completion.

It’s been nearly a year since then and he recently let it slip months back he showed half his mining crew (mostly guys in 40/50s) the video of me sucking him off. As they asked for a photo of my face and he thought he’d seem cooler to mention he had a photo with his penis in my mouth and they obviously asked to see it so he not only showed them a photo of it. But the video.

I’m absolutely fucking destroyed and could strangle him. I don’t know how to come back from this
