My Fiancé went to a strip club??

Hey ladies, sorry to rant. But I’m in a pickle right now and it’s really upsetting. Last night my Fiancé told me him and some of his buddies were bored so they wanted to go to a strip club. I expressed how uncomfortable I was with it and he seemed really understanding of my point, but he went anyways. I trust him but I trusted him to make the decision to know it would upset if he went. He said all he did was play pool til his eyes hurt (he just got eye surgery) and then waited for one of his friends to finish a lap dance in his car. I believe him, but I didn’t want him to go in the first place. That is not a place I see fit for a taken guy to hang out with his friends. We are pretty much in this long argument about it. He thinks I don’t trust him (basically trying to turn it on me) and I just want him to understand it was wrong. I have calmly stated how it made me feel. I’m not sure how to go about this. This has never happened before and we rarely fight. I don’t want to end our relationship over something dumb like this.
