Am I wrong?

I’m going through a very rough situation. A couple of days ago I ended my relationship (he’s 33 and I’m 23) because we were suppose to have a couples weekend at the hotel (which I paid for) and I made it very clear the weekend was only for us, everything was going well we had a couple of drinks and I ended up taking a nap, well when I woke up I noticed he invited his cousins whom I never met as well as their girlfriends (he even offered one of the couples to stay the night). even though I didn’t want them there I didn’t want to make a scene so I let them stay for a while, well once they began doing snorting cocaine, drinking a lot and becoming very loud and rowdy I was ready for them to leave. He began telling me what I can and can’t do, I was surprised because I’ve never saw him act that way before. To make a long story short they left at 2:30 am after one of the women threw up in the sink and got blood all over the toilet seat 🤢, while they were leaving one of the couples began fighting in the parking lot and the police were called. I was extremely embarrassed and angry because I’ve never witnessed anything like that before and I felt like what I said to him didn’t matter. I guess I want to know am I overreacting or did I have a valid reason to end the relationship?
