Brunette = Grown-up?

A few months ago I posted when I got my hair dyed dark for the first time in a long time. For the past 4 years or so I've always done blonde highlights with darker lowlights, but for the most part people would tell you my hair was blonde.
So a few months ago when I went to see my hairdresser I decided to try going dark for something different. Dark with auburn highlights and no blonde. The second I set eyes on my new hair colour I was in love. My husband was very uh...appreciative, of it too.
(The picture above is this past Wednesday - see how much it faded from the last time I dyed it?)
The weird thing is that I feel more grown up with dark hair. Up until about a year ago when someone would ask me how old I was my first thought was always 19. It seemed to me like I was 19 for about 6 years - believe me I know how dumb that sounds but it's true.
When I turned 25 I bawled and bawled. If you're like anyone else that's older than me you're probably rolling your eyes and saying "You think 25 is OLD!? Come on!"
It's not that I think 25 is old, I don't even think 65 is old - it's that I had always had this plan of where my life would be at 25 and I just wasn't there yet. I always thought I'd be married, living in a cute little house with my husband and at least one kid and working at my dream job.
But when I actually did turn 25 I was married but living in a rented townhouse with a crappy job, no money and facing infertility. Not where I wanted to be. And the worst part was that my cousin, who is the same age as me, had just finished school to become a Pharmacist (making tons of money), had bought a $250,000 house and a brand new $50,000 Chevy truck. I know it sounds petty but I was jealous - not even so much that he had all of those material possessions but more because my entire family was just like "Wow, he's really made it - look at how well he's done for himself!" He was always the one I got compared to my whole life; if he got 100% on his biology quiz and I got 96% then there had to be some sort of explanation. If he could do it then why couldn't I?
The husband has been wonderful in making me realize that although my cousin had all that stuff that he didn't have much else. He had no girlfriend, no family and really not many friends. All he did was go to work and stay home alone.
A lot has happened to me in this past year, I've gotten a wonderful job, we've been toying with the idea of buying a house in the next year or so, my husband had surgery on his back that increased his outlook on life and happiness imensely, and I finally got a specialist that is working with me on my infertility problems.
My life feels on track now and I've realized that setting a timeline for all my life's events is ridiculous - I just need to take things as they come.
Whoa, I really went on a tangent there considering this post was just supposed to be about my hair! I guess what I'm trying to say is that since I've mentally become more of an adult in the past year (I know some of my friends would beg to differ, but it's true!) that I guess my hair makes me feel more like an adult in the physical sense.
Really anything that makes my husband react in the way he does is bound to stay around for awhile!

*By the way, the above picture is very much a fake sexy pose, I assure you that I don't walk around this way and in fact as soon as I saw this picture I started to laugh so hard that I set off a coughing fit which ended in my eyes watering and me in desperate need of a Kleenex.
