Am I wrong for this?

My girl friends and I are planning a trip to Disney World when we graduate college next year. My fiancé is extremely angry with me saying it’s not fair that I will be going on a trip without him. My fiancé and I are always traveling/going on trips together but I’ve never been on a trip with my best friends, plus I make my own money so it’s not like I would be spending any of his money to go on this trip. I told him all of this but he said as a soon to be married woman I have no business going out of town for a week without him. I told him I’m going whether he wants me to or not and he basically told me if I go he will reconsider spending his life with me. My friends think he is being ridiculous and controlling. Am I wrong?
