Is my boyfriend controlling me?

I deleted my previous account, because I don't want this in any way getting back to him. Alright, things were great in the beginning. He was really attentive.. really caring. We always say that we love each other, that sort of thing. But last week, I wanted to change some things about myself. I am a natural redhead with freckles and pale skin and clear emerald green eyes. Well, I like to experiment new styles, new colors, and I always have, ever since I was around 15. Well, I just dyed my hair a chocolate brown color and started tanning, and he said he absolutely hates it. We have gotten into fights about it, because he says that I listen to everyone else but him on this matter. That it seems like I am changing things about myself because I have something to hide. I get bored with the way I look, and want a change, I don't find that there is anything wrong with that. I sometimes feel like I am stepping on eggshells around him, when he used to be so sweet in the beginning. He is also a Capricorn, and I am his polar opposite, a Cancerian, if that even matters. Also, he gets upset if I log out of all my messengers (usually we talk on Skype and Facebook when we do IM each other). And if I don't answer the phone, he complains that I am never home. He said he hates it when I make these changes, with a passion. And that it annoys him when I bring it up. But I hate fighting with him, and try my best to avoid a fight at all costs. We have known each other for years, we went to high school together, and we lost touch for a while, and we are both now about to be 28 this year. So time has definitely made change to how we are. And also, I don't know if this has to do with anything, but he is also in the military. So please. be informative as you possibly can, and only serious answers please. I don't want any games or BS. I need advice on what to do.
