Slut shaming fiancé?

So a few weekends ago my fiance and I went to town. He always comments I don't let my hair down so I did that night. I got up next to the DJ and was dancing. I was wearing a flowing top that didn't reveal my breasts and a skirt down to my knees with thick stocking and UGG heels.. but yes, I was shaking my booty having a good time! At first he was cheering for me but after a while, he told me to get down and I did. Anyway, that's not the point.. but it is part of the story. Now I have been told I have to go to Australia for work (I live in NZ) for a 3 day conference. I will leave next Monday night and work gave me the option to come home on Thursday at midnight or Friday at 9pm. I tried to tell my fiance thay I was going to take the Friday one as I would be less tired. He got angry and told me he wasn't happy with that so I said fine I'll change the flight to the midnight Thursday.. then he told me that I'd better watch out if I go and cheat and he finds out about it. Then tells me I'll go out to dinner, have a few wines, lose my inhibitions and take a guy back to my hotel. I told him I'm not like that I'm with you, and he said "I saw you up on that stage" at this point I walked off as I could tell her was getting agressive. Is this wrong?! Forgive me but I'm so caught up in the situation I need others opinions. Thanks hunnis x
