HELP! MY FIANCE HATES MY NEW STYLE, AND ITS HURTING OUR RELATIONSHIP! ?

My Fiance used to tell me that I would be beautiful no matter what. I was a bleached blonde for YEARS and I was getting sick of the stereotypes and treatment of being blonde. I'm thin and fit, with dark brown eyes, so I wanted something that would look natural, yet exotic. I spent $130 and 6 hours in the salon and got dark brown hair, and it is BEAUTIFUL! I've never had so many compliments before, it brings my eyes out and my coloring and everything! I love it! So to go with my new hair-do, I got new clothes to enhance the color, and a few y items for our alone time. My problem? My fiance hates it, and we've been having problems ever since. He says it's like he's not dating the same person. He admitts that I look better brunette, but he says that he loves me as a blonde. He constantly remarks about how "you're not going to look like that for our wedding, are you?" or "now the hoodie I bought you doesn't match your hair" and he looks at my hair and frowns. I love my hair, I feel like an individual now, instead of just some blonde, and I feel beautiful! But ever since I colored my hair, my fiance has been distant from me, and makes snappy remarks about how I'm not the same anymore (all I did was color my hair and get a few new outfits) Oh, and he thinks my "special occasion" outfit is slutty, and my playboy pants are bad taste. I just thought I would be y for him. Is hair color really that big of a deal? He was never a shallow guy, what's going on? Can I make him love my new look the way I love it, or is my only hope to go back blonde? Girls, have you experienced this? Guys, help me get in the mind of my man! Thanks :-)
