I just have to first say congrats. It's awesome that you've found "the one", and from the way you've mentioned her it sounds like you two have an awesome relationship. Then again, that's just an observation based on a few comments.
That being said, if you're ready for marriage, you're ready. Being together for so long means that you've already done a lot of growing together. Just remember that you'll both change over time, too. Change is, unfortunately, an ongoing process.
One piece of advice (granted, I'm not married yet, or engaged, so I don't know if I'm qualified to give an opinion) is to keep focused on the future. 5 years, 10 years down the road. Set goals, both individually and as a couple. And achieve them. Work together, plan together, live life together. And enjoy it as much as you can along the way. After all, life is a journey, and it sounds like you've found the person you want to share it with!
And Above All, Good Luck!!!!
Oh, the ideas!!
